Device Overview MC9S12ZVM-Family

Table 1-1. Revision History

1.1 Introduction

The MC9S12ZVM-Family is an automotive 16-bit microcontroller family using the NVM + UHV

technology that offers the capability to integrate 40 V analog components. This family reuses many

features from the existing S12/S12X portfolio. The particular differentiating features of this family are the

enhanced S12Z core, the combination of dual-ADC synchronized with PWM generation and the

integration of “high-voltage” analog modules, including the voltage regulator (VREG), Gate Drive Unit

(GDU), and either Local Interconnect Network (LIN) physical layer or CAN Physical layer . These features

enable a fully integrated single chip solution to drive up to 6 external power MOSFETs for BLDC or

PMSM motor drive applications.

The MC9S12ZVM-Family includes error correction code (ECC) on RAM and flash memory, EEPROM

for diagnostic or data storage, a fast analog-to-digital converter (ADC) and a frequency modulated phase

locked loop (IPLL) that improves the EMC performance. The MC9S12ZVM-Family allows the

integration of several key system components into a single device, optimizing system architecture and

achieving significant space savings. The MC9S12ZVM-Family delivers all the advantages and

efficiencies of a 16-bit MCU while retaining the low cost, power consumption, EMC, and code-size

efficiency advantages currently enjoyed by users of existing S12(X) families. The MC9S12ZVM-Family

is available in different pin-out options, using 80-pin, 64-pin and 48-pin LQFP-EP packages to

accommodate LIN, CAN and external PWM based application interfaces. In addition to the I/O ports

available in each module, further I/O ports are available with interrupt capability allowing wake-up from

stop or wait modes.

The MC9S12ZVM-Family is a general-purpose family of devices suitable for a range of applications,

including:

• 3-phase sensorless BLDC motor control for

— Fuel pump

The pins are the low-side drain connections for the low-side power FETs. The pins can be used to monitor

the low-side power FETs for desaturation conditions.

1.7.2.27.9 CP - Charge Pump Output Signal

This pin is the switching node of the charge pump circuit. The supply voltage for charge pump driver is

the output of the voltage regulator VLS_OUT. The output voltage of this pin switches typically between

0V and 11V. Must be left unconnected if not used.

1.7.2.27.10 VCP - Charge Pump Input For High-Side Driver Supply

This is the charge pump input for the FET high-side gate drive supply circuit. The pin must be left

unconnected if not used.

1.7.2.27.11 BST - Boost Signal

This pin provides the basic switching elements required to implement a boost converter for low battery

voltage conditions. This requires external diodes, capacitors and a coil. This pin must be left unconnected

if not used.

The boost function must not be used on devices of the maskset 2N95G, because these devices use the

VSUP pin as the LINPHY supply. Thus boosting the VSUP voltage can cause LIN supply voltage offsets

to other devices on the LIN bus.

1.7.2.27.12 VSSB - Boost Ground Signal

This pin is a separate ground pin for the on chip boost converter switching device.

1.7.2.27.13 VLS_OUT - 11V Voltage Regulator Output

This pin is the output of the integrated voltage regulator. The output voltage is typically VVLS=11V. The

input voltage to the voltage regulator is the VSUP pin.

1.7.2.27.14 AMPP[1:0] - Current Sense Amplifier Non-Inverting Input

These are the current sense amplifier non-inverting inputs.

1.7.2.27.15 AMPM[1:0] - Current Sense Amplifier Inverting Input

These are the current sense amplifier inverting inputs.

1.7.2.27.16 AMP[1:0] - Current Sense Amplifier Output

These are the current sense amplifier outputs.

1.7.2.28 High Current Output — EVDD1

This is a high current, low voltage drop output intended for supplying external devices in a range of up to

20mA. Configuring the pin direction as output automatically enables the high current capability.

1.7.3 Power Supply And Voltage Regulator Related Pins

The power and ground pins are described below. Because fast signal transitions place high, short-duration

current demands on the power supply , use bypass capacitors with high-frequency characteristics and place

them as close to the MCU as possible.

NOTE

All ground pins must be connected together in the application.

1.7.3.1 VDDX1, VDDX2, VSSX1 — Digital I/O Power and Ground Pins

VDDX1, VDDX2 are voltage regulator outputs to supply the digital I/O drivers.

The VSSX1 pin is the ground pin for the digital I/O drivers.

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

46 Freescale Semiconductor

Bypass requirements on VDDX2, VDDX1, VSSX1 depend on how heavily the MCU pins are loaded.

1.7.3.2 BCTL

BCTL is the ballast connection for the on chip voltage regulator . It provides the base current of an external

bipolar for the VDDX and VDDA supplies. If not used BCTL should be left unconnected.

1.7.3.3 VDDA, VSSA — Power Supply Pins For ADC

These are the power supply and ground pins for the analog-to-digital converter and the voltage regulator.

1.7.3.4 VDD, VSS2 — Core Power And Ground Pins

The VDD voltage supply of nominally 1.8V is generated by the internal voltage regulator. The return

current path is through the VSS1 pin on ZVMC256, or VSS2 pin on other devices.

1.7.3.5 VDDF, VSS1— NVM Power And Ground Pins

The VDDF voltage supply of nominally 2.8V is generated by the internal voltage regulator . The return path

is through the VSS1 pin. On ZVMC256, the return current path is through the VSS1 and VSSX pins.

1.7.3.6 VSUP — Voltage Supply Pin for Voltage Regulator

VSUP is the main supply pin typically coming from the car battery/alternator in the 12V supply voltage

range. This is the voltage supply input from which the voltage regulator generates the on chip voltage

supplies. It must be protected externally against a reverse battery connection.

1.7.3.7 VDDS1 — 5V Supply Pin For External Devices (ZVMC256 Only)

This provides a regulated, short circuit protected, 5V supply for external devices. This is the output voltage

of the external bipolar, whose base current is supplied by BCTLS1. It is fed back to the MCU for

regulation.

1.7.3.8 BCTLS1 (ZVMC256 Only)

BCTLS1 provides the base current of an external bipolar that supplies VDDS1. If not used BCTLS1

should be left unconnected.

1.7.3.9 SNPS1 (ZVMC256 Only)

SNPS1 is the sense input associated with the VDDS1 regulator. The voltage regulator uses it to detect a

short circuit or over current condition.

1.7.3.10 VDDS2 — 5V Supply Pin For External Devices (ZVMC256 Only)

This provides a regulated, short circuit protected, 5V supply for external devices. This is the output voltage

of the external bipolar, whose base current is supplied by BCTLS2. It is fed back to the MCU for

regulation.

MC9S12ZVM Family Reference Manual Rev. 2.2

Freescale Semiconductor 47

1.7.3.11 BCTLS2 (ZVMC256 Only)

BCTLS2 provides the base current of an external bipolar that supplies VDDS2. If not used BCTLS2

should be left unconnected.

1.7.3.12 SNPS2 (ZVMC256 Only)

SNPS2 is the sense input associated with the VDDS2 regulator. The voltage regulator uses it to detect a

short circuit or over current condition.

1.7.4 Package and Pinouts

The following package options are offered.

• 80LQFP-EP (exposed pad) with internal CANPHY and CAN VREG.

• 64LQFP-EP (exposed pad) with internal LINPHY or HV physical interface.

• 64LQFP-EP (exposed pad) with CAN VREG to support a low cost external CANPHY.

• 48LQFP-EP (exposed pad)

The exposed pad must be connected to a grounded contact pad on the PCB.

The exposed pad has an electrical connection within the package to VSSFLAG (VSSX die connection).

The pin out details are shown in the following diagrams. Signals in brackets denote routing options.

1.8 Internal Signal Mapping

This section specifies the mapping of inter- module signals at device level.

1.8.1 ADC Connectivity

1.8.1.1 ADC Reference Voltages

The ZVMC256 includes ADC12B_LBA V3 which features VRH_2, VRH_1, VRH_0 and VRL_0. On

these devices for each ADC instance VRH_0 is mapped to VDDA, VRH_1 is mapped to VDDS1 and

VRH_2 is mapped to VDDS2. VRL_0 is mapped to VSSA. Both VDDS1 and VDDS2 must be enabled

by bits in the CPMUVREGCTL register before they can be used as references.

All other devices in the family include ADC12B_LBA V1, which features VRH_1, VRH_0, VRL_1 and

VRL_0. On these devices, for both ADC instances, VRL_0 and VRL_1 are mapped to VSSA, whereby

VRL_0 is the preferred reference for low noise. For both ADC instances VRH_1 is mapped to VDDA and

VRH_0 is mapped to PAD8.

1.8.1.2 ADC Internal Channels

The ADC0 and ADC1 internal channel mapping is shown in Table 1-10 and Table 1-11 respectively.

The GDU current sense amplifier outputs are mapped to pins with ADC input functionality. Thus

configuring the ADC to convert these pin channels automatically converts the current sense outputs.

The ADC internal temperature sensors must be calibrated by the user. No electrical parameters are

specified for these sensors. The VREG temperature sensor electrical parameters are given in the

appendices.

The motor control loop signals are described in 1.13.3.1 Motor Control Loop Overview

1.8.3 Device Level PMF Connectivity

1.8.4 BDC Clock Source Connectivity

The BDC clock, BDCCLK, is mapped to the IRCCLK generated in the CPMU module.

1.8.5 LINPHY Connectivity

The VLINSUP supply is device dependent.

On ZVML128, ZVMC128, ZVML64, ZVMC64 and ZVML32 devices with the maskset number 2N95G

it is connected to VSUP

On all other devices it is connected to the device HD pin.

The LINPHY0 signals are mapped internally to SCI0. The receiver can be routed to TIM0 input capture

channel3. These routing options are described in detail in the PIM section.

1.8.6 HVPHY Connectivity

The HVPHY signals (S12ZVM32 and S12ZVM16 derivatives only) are mapped internally to SCI0. The

receiver can be routed to TIM0 input capture channel3.

1.8.7 FTMRZ Connectivity

The soc_erase_all_req input to the flash module is driven directly by a BDC erase flash request resulting

from the BDC ERASE_FLASH command.

The FTMRZ FCLKDIV register is forced to 0x05 by the BDC ERASE_FLASH command. This

configures the clock frequency correctly for the initial bus frequency on leaving reset. The bus frequency

must not be changed before launching the ERASE_FLASH command.

The device bus frequency, below which the flash wait states can be disabled, is specified in the device

operating conditions table in Table A-6.

1.8.8 CPMU Connectivity

The API clock generated in the CPMU is not mapped to a device pin in the MC9S12ZVM-Family.

1.9 Modes of Operation

The MCU can operate in different modes. These are described in 1.9.1 Chip Configuration Modes.

The MCU can operate in different power modes to facilitate power saving when full system performance

is not required. These are described in 1.9.3 Low Power Modes.

Some modules feature a software programmable option to freeze the module status whilst the background

debug module is active to facilitate debugging. This is referred to as freeze mode at module level.

1.9.1 Chip Configuration Modes

The different modes and the security state of the MCU affect the debug features (enabled or disabled).

The operating mode out of reset is determined by the state of the MODC signal during reset (Table 1-13).

The MODC bit in the MODE register shows the current operating mode and provides limited mode

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

Freescale Semiconductor 61

switching during operation. The state of the MODC signal is latched into this bit on the rising edge of

RESET.

1.9.1.1 Normal Single-Chip Mode

This mode is intended for normal device operation. The opcode from the on-chip memory is being

executed after reset (requires the reset vector to be programmed correctly). The processor program is

executed from internal memory.

1.9.1.2 Special Single-Chip Mode

This mode is used for debugging operation, boot-strapping, or security related operations. The background

debug mode (BDM) is active on leaving reset in this mode

1.9.2 Debugging Modes

The background debug mode (BDM) can be activated by the BDC module or directly when resetting into

Special Single-Chip mode. Detailed information can be found in the BDC module section.

Writing to internal memory locations using the debugger, whilst code is running or at a breakpoint, can

change the flow of application code.

The MC9S12ZVM-Family supports BDC communication throughout the device Stop mode. During S top

mode, writes to control registers can alter the operation and lead to unexpected results. It is thus

recommended not to reconfigure the peripherals during STOP using the debugger.

On the S12ZVML and S12ZVMC versions, the DBG module supports breakpoint, tracing and profiling

features. At board level the profiling pins can use the same 6-pin connector typically used for the BDC

BKGD pin. The connector pin mapping shown in Figure 1-7 is supported by device evaluation boards and

leading development tool vendors.

Figure 1-7. Standard Debug Connector Pin Mapping

1.9.3 Low Power Modes

The device has two dynamic-power modes (run and wait) and two static low-power modes stop and pseudo

stop). For a detailed description refer to the CPMU section.

62 Freescale Semiconductor

• Dynamic power mode: Run

— Run mode is the main full performance operating mode with the entire device clocked. The user

can configure the device operating speed through selection of the clock source and the phase

locked loop (PLL) frequency. To save power, unused peripherals must not be enabled.

• Dynamic power mode: Wait

— This mode is entered when the CPU executes the WAI instruction. In this mode the CPU does

not execute instructions. The internal CPU clock is switched of f. All peripherals can be active

in system wait mode. For further power consumption the peripherals can individually turn off

their local clocks. Asserting RESET, XIRQ, IRQ, or any other interrupt that is not masked,

either locally or globally by a CCR bit, ends system wait mode.

• Static power modes:

Static power (Stop) modes are entered following the CPU STOP instruction unless an NVM

command is active. When no NVM commands are active, the Stop request is acknowledged and

the device enters either Stop or Pseudo Stop mode. Further to the general system aspects of Stop

mode discussed here, the motor control loop specific considerations are described in

Section 1.13.3.10.

— Pseudo-stop: In this mode the system clocks are stopped but the oscillator is still running and

the real time interrupt (RTI), watchdog (COP) and Autonomous Periodic Interrupt (API) may

be enabled. Other peripherals are turned off. This mode consumes more current than system

STOP mode but, as the oscillator continues to run, the full speed wake up time from this mode

is significantly shorter.

— Stop: In this mode the oscillator is stopped and clocks are switched off. The counters and

dividers remain frozen. The autonomous periodic interrupt (API) may remain active but has a

very low power consumption. The key pad, SCI and MSCAN transceiver modules can be

configured to wake the device, whereby current consumption is negligible.

If the BDC is enabled in Stop mode, the VREG remains in full performance mode and the

CPMU continues operation as in run mode. With BDC enabled and BDCCIS bit set, then all

clocks remain active to allow BDC access to internal peripherals. If the BDC is enabled and

BDCCIS is clear, then the BDCSI clock remains active, but bus and core clocks are disabled.

With the BDC enabled during Stop, the VREG fu ll performance mode and clock activity lead

to higher current consumption than with BDC disabled. If the BDC is enabled in Stop mode,

then the BATS voltage monitoring remains enabled.

1.10 Security

The MCU security mechanism prevents unauthorized access to the flash me mory. It must be emphasized

that part of the security must lie with the application code. An extreme example would be application code

that dumps the contents of the internal memory. This would defeat the purpose of security. Also, if an

application has the capability of downloading code through a serial port and then executing that code (e.g.

an application containing bootloader code), then this capability could potentially be used to read the

EEPROM and Flash memory contents even when the microcontroller is in the secure state. In this

example, the security of the application could be enhanced by requiring a response authentication before

any code can be downloaded.

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

Freescale Semiconductor 63

Device security details are also described in the flash block description.

1.10.1 Features

The security features of the S12Z chip family are:

• Prevent external access of the non-volatile memories (Flash, EEPROM) content

• Restrict execution of NVM commands

1.10.2 Securing the Microcontroller

The chip can be secured by programming the security bits located in the options/security byte in the Flash

memory array. These non-volatile bits keep the device secured through reset and power-down.

This byte can be erased and programmed like any other Flash location. Two bits of this byte are used for

security (SEC[1:0]). The contents of this byte are copied into the Flash security register (FSEC) during a

reset sequence.

The meaning of the security bits SEC[1:0] is shown in Table 1-14. For security reasons, the state of device

security is controlled by two bits. To put the device in unsecured mode, these bits must be programmed to

SEC[1:0] = ‘10’. All other combinations put the device in a secured mode. The recommended value to put

the device in secured state is the inverse of the unsecured state, i.e. SEC[1:0] = ‘01’.

NOTE

Please refer to the Flash block description for more security byte details.

1.10.3 Operation of the Secured Microcontroller

By securing the device, unauthorized access to the EEPROM and Flash memory contents is prevented.

Secured operation has the following effects on the microcontroller:

1.10.3.1 Normal Single Chip Mode (NS)

• Background debug controller (BDC) operation is completely disabled.

• Execution of Flash and EEPROM commands is restricted (described in flash block description).

1.10.3.2 Special Single Chip Mode (SS)

• Background debug controller (BDC) commands are restricted

• Execution of Flash and EEPROM commands is restricted (described in flash block description).

01 1 (secured)

10 0 (unsec ur e d)

11 1 (secured)

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

64 Freescale Semiconductor

In special single chip mode the device is in active BDM after reset. In special single chip mode on a secure

device, only the BDC mass erase and BDC control and status register commands are possible. BDC access

to memory mapped resources is disabled. The BDC can only be used to erase the EEPROM and Flash

memory without giving access to their contents.

1.10.4 Unsecuring the Microcontroller

Unsecuring the microcontroller can be done using three different methods:

1. Backdoor key access

2. Reprogramming the security bits

3. Complete memory erase

1.10.4.1 Unsecuring the MCU Using the Backdoor Key Access

In normal single chip mode, security can be temporarily disabled using the backdoor key access method.

This method requires that:

• The backdoor key has been programmed to a valid value

• The KEYEN[1:0] bits within the Flash options/security byte select ‘enabled’.

• The application program programmed into the microcontroller has the capability to write to the

backdoor key locations

The backdoor key values themselves would not normally be stored within the application data, which

means the application program would have to be designed to receive the backdoor key values from an

external source (e.g. through a serial port)

The backdoor key access method allows debugging of a secured microcontroller without having to erase

the Flash. This is particularly useful for failure analysis.

NOTE

No backdoor key word is allowed to have the value 0x0000 or 0xFFFF.

1.10.5 Reprogramming the Security Bits

Security can also be disabled by erasing and reprogramming the security bits within the flash

options/security byte to the unsecured value. Since the erase operation will erase the entire sector

(0xFF_FE00–0xFF_FFFF) the backdoor key and the interrupt vectors will also be erased; this method is

not recommended for normal single chip mode. The application software can only erase and program the

Flash options/security byte if the Flash sector containing the Flash options/security byte is not protected

(see Flash protection). Thus Flash protection is a useful means of preventing this method. The

microcontroller enters the unsecured state after the next reset following the programming of the security

bits to the unsecured value.

This method requires that:

• The application software previously programmed into the microcontroller has been designed to

have the capability to erase and program the Flash options/security byte.

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

Freescale Semiconductor 65

• The Flash sector containing the Flash options/security byte is not protected.

1.10.6 Complete Memory Erase

The microcontroller can be unsecured by erasing the entire EEPROM and Flash memory contents. If

ERASE_FLASH is successfully completed, then the Flash unsecures the device and programs the security

byte automatically.

On each reset, the Flash module executes a reset sequence to load Flash configuration registers.

1.11.3.1 Flash Configuration Reset Sequence Phase

On each reset, the Flash module will hold CPU activity while loading Flash module registers from the

Flash memory. If double faults are detected in the reset phase, Flash module protection and security may

be active on leaving reset. This is explained in more detail in the Flash module description.

1.11.3.2 Reset While Flash Command Active

If a reset occurs while any Flash command is in progress, that command will be immediately aborted. The

state of the word being programmed or the sector/block being erased is not guaranteed.

1.11.3.3 I/O Pins

Refer to the PIM section for reset configurations of all peripheral module ports.

1.11.3.4 RAM

The system RAM arrays, including their ECC syndromes, are initialized following a power on reset. All

other RAM arrays are not initialized out of any type of reset.

With the exception of a power-on-reset the RAM content is unaltered by a reset occurrence.

1.12 Module device level dependencies

1.12.1 CPMU COP and GDU GSUF Configuration

The COP time-out rate bits CR[2:0] and the WCOP bit in the CPMUCOP register are loaded fro m the

Flash configuration field byte at global address 0xFF_FE0E during the reset sequence. On the device

1.12.2 CPMU High Temperature Trimming

The value loaded from the flash into the CPMUHTTR register is a default value for the device family.

There is no device specific trimming carried out during production. The specified VHT value is a typical

value that is part dependent and should thus be calibrated.

1.13 Application Information

1.13.1 ADC Calibration

For applications that do not provide external ADC reference voltages, the VDDA/VSSA supplies can be

used as sources for VRH/VRL respectively. Since the VDDA must be connected to VDDX at board level

in the application, the accuracy of the VDDA reference is limited by the internal voltage regulator

accuracy. In order to compensate for VDDA reference voltage variation in this case, the reference voltage

is measured during production test using the internal reference voltage VBG, which has a narrow variation

over temperature and external voltage supply. VBG is mapped to an internal channel of each ADC module

(Table 1-10,Table 1-11). The resulting 12-bit right justified ADC conversion results of VBG are stored to

the flash IFR for reference, as listed in Table 1-20.

The measurement conditions of the reference conversion are listed in the device electrical parameters

appendix. By measuring the voltage VBG in the application environment and comparing the result to the

reference value in the IFR, it is possible to determine the current ADC reference voltage VRH :

The exact absolute value of an analog conversion can be determined as follows:

With:

ConvertedADInput: Result of the analog to digital conversion of the desired pin

ConvertedReference: Result of internal channel conversion

n: ADC resolution (12 bit)

NOTE

The ADC reference voltage VRH must remain at a constant level throughout

the conversion process.

1.13.2 SCI Baud Rate Detection

The baud rate for SCI0 and SCI1 is achieved by using a timer channel to measure the data rate on the RXD

signal.

1. Establish the link:

— For SCI0: Set [T0IC3RR1:T0IC3RR0]=0b01 to disconnect IOC0_3 from TIM0 input capture

channel 3 and reroute the timer input to the RXD0 signal of SCI0.

— For SCI1: Set [T0IC3RR1:T0IC3RR0]=0b10 to disconnect IOC0_3 from TIM0 input capture

channel 3 and reroute the timer input to the RXD1 signal of SCI1.

2. Determine pulse width of incoming data: Configure TIM0 IC3 to measure time between incoming

signal edges.

1.13.3.1 Motor Control Loop Overview

The mapping of motor control events at device level as depicted in Figure 1-8 is listed in Table 1-21,

whereby the columns list the names used in the module level descriptions

Figure 1-8. Internal Control Loop Configuration

The control loop consists of the PMF, GDU, ADC and PTU modules. The control loop operates using

either static, dynamic or asynchronous timing. In the following text the event names given in bold type

correspond to those shown in Figure 1-8. The PTU and ADC operate using lists stored in memory. These

lists define trigger points for the PTU, commands for the ADC and results from the ADC. If the PTU is

enabled the reload and async_reload events are immediately passed through to the ADC and GDU

modules.

Each control loop cycle is started by a PMF reload event. The PMF reload event restarts the PTU time

base. If the PTU is enabled, the reload is immediately passed through to the ADC and GDU modules.

The PMF generates the reload event at the required PWM reload frequency. The PMF reload event causes

the PTU time base to restart, to acquire the first trigger times from the list and the ADCs to start loading

the ADC conversion command from the Command Sequence List (CSL).

NOTE

In the PTU there is time window after the reload event assertion before the

first trigger is permitted. This time can be up to 10 bus cycles.

Subsequent triggers also require a load time of 6 bus clock cycles (one

trigger generator enabled) or 10 bus clock cycles (both trigger generators

enabled). This defines the minimal spacing between triggers without

causing a PTU trigger generator timing error.

In the ADC there is 10 bus cycle maximum time window after the reload

event assertion to access the first ADC command from the list. In this

window the ADC conversion can not be started. If the measurement is

control loop related these delays are negligible due to much larger delays in

the PWM-GDU-feedback loop.

When the trigger time is encountered the corresponding PTU trigger generates the trigger_x event for the

associated ADC. For simultaneous sampling the PTU generates simultaneous trigger_x events for both

ADCs. At the trigger_x event the ADC starts the first conversion of the next conversion sequence in the

CSL (the first ADC command is already downloaded).

A commutation event is used by the PMF to generate an async_reload event. The async_reload is used by

the PTU to update lists and re-initialize the trigger lists. If the PTU is enabled the async_reload is

immediately passed through to the ADC.

1.13.3.2 Control Loop Timing Considerations

Delays within the separate control loop elements require consideration to ensure correct synchronization.

Regarding the raw PWM0 signal as the starting point and stepping through the control loop stages, the

factors shown in Figure 1-9 contribute to delays within the control loop, starting with the deadtime

insertion, going through the external FETs and back into the internal ADC measurements of external

voltages and currents.

Figure 1-9. Control Loop Delay Overview

The PWM deadtime (TDEAD_X) is an integral number of bus clock cycles, configured by the PMF

deadtime registers.

The GDU propagation delays (tdelon, tdeloff) are specified in the electrical parameter Table E-1.

The FET turn on times (tHGON) are load dependent but are specified for particular loads in the electrical

parameter Table E-1.

The current sense amplifier delay is highly dependent on external components.

The ADC delay until a result is available is specified as the conversion period NCONV in Table C-1.

1.13.3.3 Static Timing Operation

The timing frame is static if it is the same in every control cycle (defined by reload frequency) and is

relative to start of the control cycle. The only settings modified from one control cycle to the next one are

the PWM duty cycle registers.

The main control cycle synchronization event is the PMF reload event. The PMF reload event can be

generated every n PWM periods.

This mode can optionally be extended by a timer channel trigger to PMF to change the PWM channel

operation (e.g. used for BLDCM commutation). In this case, the PMF configuration can propagate the

PWM with

trigger through the control loop or can prevent propagation so the static timing of the control cycle and

inter-block coherency are not affected by the trigger.

At the end of the conversion sequence the first ADC command from the new sequence is loaded and the

ADCx waits for the next trigger_x. The PTU continues to generate the trigger_x events for each trigger

time from the list until a new reload or async_reload occurs.

Before the upcoming reload event the CPU:

• reads the ADC results from the buffered Conversion Result List

• clears the conversion complete flag

• services the reload by setting new duty cycle values

• sets the PTULDOK bit (corresponding to glb_ldok) to signal the duty cycle coherence

The CPU actions are typically performed in an ISR triggered by the conversion complete flag.

1.13.3.4 Static Timing Fault Handling

The following Faults and/or errors can occur:

• Desaturation error, Overvoltage, Undervoltage, Temperature sensor, External fault

The application run-time error is handled by the GDU without CPU interaction. Firstly the FETs are

disabled and the PMF signals switched to an inactive state. To re-enable the operation first the GDU fault

and then PWM fault must be cleared, to automatically re-enable the FET driving at the next PWM

boundary.

• PTU reload overrun error

This is an application run-time error caused by the CPU not setting PTULDOK on time. Servicing this type

of error is application dependent and may range from a further reload attempt to a total shut down.

• PTU trigger generator reload error, PTU trigger generator error

Since all timing is static, this error should only occur during application debugging. This type of error

occurring in a static timing configuration indicates possible data corruption. This can be serviced by a

control loop shutdown.

• PTU memory access error, Memory access double bit ECC error

This type of error occurring in an application indicates data corruption. This can be serviced by a control

loop shutdown.

• ADC sequence overrun, ADC command overrun, ADC command error

Since all timing is static, this error should only occur during application debugging. This type of error

occurring in an application indicates possible data corruption. This can be serviced by a control loop

shutdown.

1.13.3.5 Dynamic Timing Operation

The timing frame is dynamic if the following are modified on a cycle by cycle basis:

• PMF - duty cycle value registers (PMF_VALx), modulo registers

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

Freescale Semiconductor 77

• PTU - Trigger Event List (PTU_TELx)

• ADC - Command Sequence List (ADCx_CSL)

The main philosophy is that all cycle-by-cycle settings for cycle n need to be done within cycle n-1. The

main control cycle synchronization event is the PMF reload event, which can be generated every n PWM

periods.

This mode can optionally be extended by a timer channel trigger PMF to change PWM channel operation

(e.g. used for BLDCM commutation).

The event flow is the same as for static timing.

Before the upcoming reload event the CPU:

• reads the ADC results from the buffered Conversion Result List

• clears the conversion complete flag

• services the reload by setting new duty cycle values and a new PMF modulo value

• updates the non-active PTU_TELx

• updates the non-active ADCx_CSL

• sets the PTULDOK bit (corresponding to glb_ldok) to signal the duty cycle coherence

The CPU actions are typically performed in an ISR triggered by the conversion complete flag.

1.13.3.6 Dynamic Timing Fault Handling

The following Faults and/or errors can occur:

• Desaturation error, Overvoltage, Undervoltage, Temperature sensor, External fault

The application run-time error is handled by the GDU without CPU interaction. Firstly the FETs are

disabled and the PMF signals switched to an inactive state. To re-enable the operation first the GDU fault

and then PWM fault must be cleared, to automatically re-enable the FET driving at the next PWM

boundary.

• PTU reload overrun error

This is an application run-time error caused by the CPU not setting PTULDOK on time. Servicing this type

of error is application dependent and may range from a further reload attempt to a total shut down.

• PTU trigger generator reload error, PTU trigger generator error

This indicates an application run-time error caused by a settings mismatch. Servicing this type of error is

application dependent. In some cases, the ADC values for the current control cycle can be ignored.

• PTU memory access error, Memory access double bit ECC error

This type of error occurring in an application indicates possible data corruption. This can be serviced by a

control loop shutdown.

• ADC sequence overrun, ADC command overrun, ADC command error

This indicates an application run-time error caused by a settings mismatch. Servicing this type of error is

application dependent. In some cases, the ADC values for the current control cycle can be ignored.

1.13.3.7 Asynchronous Timing

This case is an extension of the dynamic timing case by an asynchronous event generated by the Timer.

Note the asynchronous term is referenced to the control cycle.

The timing frame is the same as in dynamic timing case plus it can be asynchronously restarted at any time

within the control cycle.

At the asynchronous commutation_event

• the PMF actions are:

1. counter re-start, re-initialization

2. PWM configuration re-initialization according to the selected PWM settings (c enter/edge-aligned

pattern, normal/inverted type etc.)

3. re-initialization of the dead time generators (in case the commutation takes place at a time when

one of the dead times is being generated)

4. re-initialization of the PWM outputs according to pre-set PWM channel output settings in double

buffered registers (mask, swap, output control)

5. re-initialization of the automatic fault clearing

6. generates async_reload event for the PTU

7. optionally updates the PWM duty cycle values based on LDOK state

• the PTU actions are:

1. abortion of the trigger_x event generation

2. re-initialization and re-start the PTU counter

3. update of the current list index TGxList based on the glb_ldok state

4. fetch first trigger time from updated TGxList

5. passes the async_reload event immediately to the ADC (if the PTU is enabled)

6. generates the reload event for the ADC

• the ADC actions are:

1. the conversion in progress is completed

2. the ADC conversion sequence is aborted and the SEQA flag is set to indicate that the final

conversion occurred during the abortion process (potentially coinciding with a commutation and

is thus less precise than under normal conditions)

3. update of the current lists index ADxLists

4. re-start of the conversion sequencing upon successful abortion - fetches the first ADC command

from the ADCx_CSL, re-sets the result pointer to the top of the list

Note: in case the lists index ADxLists is not updated at the sequence abortion the new restarted

A/D conversions will overwrite the previously converted results.

• the GDU actions are:

1. standard operation

1.13.3.8 Control Loop Startup Guidelines

The sequence for control loop start up is to firstly configure the signal measurement (inputs/feedback).

Once the measurement is properly configured (correct value is measured at defined time) the output

actuation (control action) is configured. The following modules are involved in signal measurements.

• TIM (to identify asynchronous commutation) [BLDC applications only]

• PMF (to generate main synchronous events for PTU and ADC)

• PTU (to generate delay relative to synchronous events generated by PMF)

• ADC (to acquire analog signals under synchronous control)

• GDU (zero crossing comparators, Back-EMF muxing) [application dependent]

The TIM OC0 channel identifies the commutation event and restarts the PMF counter . In order to establish

this link TIM and PMF need to be configured and started. Then to sample accurately within one PMF cycle

the PTU needs to be used, so the next step is to configure the PTU to establish PMF to PTU link. The PTU

sends triggers to the ADC to perform a measurement of control signals. So the next step is to configure the

ADC. In some cases the GDU involvement is required and therefore configured.

The control action involves the PMF (to generate the duty cycle for GDU) and the GDU (to propagate the

signal to the MOSFET s). Since the PMF has already been configured for the measurements, only the GDU

need be configured to complete startup. Sometimes the GDU can be configured earlier but the GDU output

is always enabled last.

The recommended startup sequence is summarized as follows:

• Configure TIM and PMF to establish the link between TIM OC0 commutation event and PMF

• Configure PTU to establish the PMF to PTU link and ensure correct sampling within PMF cycle

• Configure the ADC

• Configure the GDU

1.13.3.9 Control Loop Shutdown Guidelines

1. Remove energy stored in the system after the power stage

kinetic energy - stop all rotating/moving mass

magnetic energy - gracefully drive currents to zero

2. Put GDU and PMF outputs to safe state

1.13.3.10 Control Loop Stop Mode Considerations

In Stop mode the PMF, PTU, ADC can not run because the bus clock is not running. Thus the GDU must

transition to a disabled state. Before entering S top mode the application must perform the following steps:

1. Remove energy stored in the system after the power stage

kinetic energy - stop all rotating/moving mass

magnetic energy - gracefully drive currents to zero

2. Put GDU and PMF outputs to safe state

3. Verify GDU and PMF safe states

Chapter 1 Device Overview MC9S12ZVM-Family

MC9S12ZVM Family Reference Manual Rev. 2.2

80 Freescale Semiconductor

4. Verify fault flags and service if necessary

5. Execute the STOP instruction

The return from stop is expected in reverse order:

1. On returning from Stop mode the clocks are automatically enabled coherently

2. Initialize and check device proper functionality (charge pump etc.)

3. Check functionality of the external system

4. Initializes control loop operation, however with PMF and GDU outputs still in safe state

5. Read the ADC values to check the system

6. Start driving energy into the system

based on the measurements from the previous step, the PWM duty cycle values are calculated

7. PMF and GDU outputs are enabled (actively driven)

The device does not support putting the FETs in an active driving state during STOP as the GDU charge

pump clock is not running. This means the device cannot be put in stop mode if the FETS need to be in an

active driving state to protect the system from external energy supply (e.g. externally driven motor-

generator).

NOTE

It is imperative, that whatever the modules perform on entering/exiting Stop

mode, the pre-set complementary mode of operation and dead time insertion

must be guaranteed all the times.

1.13.3.11 Application Signal Visibility

In typical motor control applications, TIM OC0 is used internally to indicate commutation events. To

switch off OC0 visibility at port pin PT0:

• Disable output compare signal on pin PT0 in TIM: OCPD[OCPD0]=0b1.

1.13.3.12 Debug Signal Visibility

Depending on required visibility of internal signals on port pins enable the following registers:

• Set [PWMPRR]=0b1 in PIM if monitoring of internal PWM waveforms is needed. PWM0_[5:3]

are driven out on pins PT[2:0] and PWM0_[2:0] on pins PP[2:0].

• Enable output compare channel OC0 to output commutation event on pin PT0 in TIM:

OCPD[OCPD0]=0b0.

• Set PTUDEBUG[PTUREPE]=0b1 in PTU to output the reload event.

• Set PTUDEBUG[PTUTxPE]=0b1 with x=0,1 in PTU to output the trigger events.

1.13.4 BDCM Complementary Mode Operation

This section describes BDCM control using center aligned complementary mode with deadtime insertion.

Freescale Semiconductor 81

The DC Brushed motor power stage topology is a classical full bridge as shown in Figure 1-10. The DC

Brushed motor is driven by the DC voltage source. A rotational field is created by means of commutator

and brushes on the motor. These drives are still very popular because sophisticated calculations and

algorithms such as commutation, waveform generation, or space vector modulation are not required.

Figure 1-10. DC Brushed Motor External Configuration

Usually the control consists of an outer, speed control loop with inner current (torque) control loop. The

inner loop controls DC voltage applied onto the motor winding. The control loop is calculated regularly

within a given period. In most cases, this period matches the PWM reload period.

Driving the DC motor from a DC voltage source, the motor can work in all four quadrants. The

complementary mode of operation with deadtime insertion is needed for smooth reversal of the motor

current (motor torque), hence smooth full four quadrant control. Usually the center-aligned PWM is

chosen to lower electromagnetic emissions.

Figure 1-11. BDCM Control Loop Configuration

The PWM frequency selection is always a compromise between audible noise, electromagnetic emissions,

current ripples and power switching losses.

The BDCM control loop goal is to provide a controlled DC voltage to the motor winding, whereby it is

controlled cycle-by-cycle using a speed, current or torque feedback loop.

The center aligned PWM waveforms generated by the PMF module are applied to the bridge as shown in

Figure 1-12 whereby the base waveform for PWM0_0 and PWM0_1 is depicted at the top and the

complementary PWM0_0 and PWM0_1 waveforms are shown with deadtime insertion depicted by the

Assuming first quadrant operation, forward accelerating operation, the applied voltage at node A must

exceed the applied voltage at node B (Figure 1-10). Thus the PWM0_0 duty cycle must exceed the

PWM0_2 duty cycle.

The duty cycle of PWM0_0 defines the voltage at the first power stage branch.

The duty cycle of PWM0_2 defines the voltage at the second power stage branch.

Modulating the duty cycle every period using the function FPWM then the duty cycle is expressed as:

PWM0_0 duty-cycle = 0.5 + (0.5 * FPWM); For -1<=FPWM <= 1;

1.13.5.1 Hall Sensor Triggered Commutation

Figure 1-13. BLDC Configuration With Hall Sensors

This BLDC application uses Hall sensor signals to create commutation triggers. The integrated sense

amplifier and an ADC module are used to measure DC bus current, for torque calculation. The DC bus

voltage measurement is used in the control algorithm to counter-modulate the PWM such that the variation

of the DC-bus voltage does not affect the motor current closed loop. The configuration is as follows:

1. Connect the three Hall sensor signals from the motor to input pins PT3-1.

2. Set [T0IC1RR=1] in the register MODRR2 to establish the link from Hall sensor input pins to TIM

input capture channel 1.

3. Setup TIM IC1 for speed measurement of XORed Hall sensor signals. Enable interrupt on both

edges.

4. Enable TIM OC0 and select toggle action on output compare event: TCTL2[OM0:OL0]=01.

5. Configure PMF for edge-aligned PWM mode with or without restart at commutation:

PMFENCx[RSTR T]. If using the restart option, then select generator A as reload signal source and

keep the following configurations at their default setting: multi timebase generators

(PMFCFG0[MTG]=b0), reload frequency (PMFFQCx[LDFQx]=b0), prescaler

(PMFFQCx[PRSCx]=b00).

To calculate the commutation time in a sensorless motor system the back-EMF zero crossing event of the

currently non-fed phase within an electrical rotation cycle must be determined. For fast motor rotation, the

ADC is used to measure the back-EMF voltage and the DC bus voltage to determine the zero crossing time.

For slow motor rotation the GPHS register can be polled. In either case the zero crossing event is handled

6. Take samples of the phase voltages periodically based on PWM cycle to detect zero crossing.

7. Calculate the delay to next commutation and store value to output compare register. Update

registers with next values of mask and swap.

PMSM control drives all 3 phases simultaneously with sinusoidal waveforms. Both sensorless and Sine-

Cosine position sensor control loop operation are supported.

1.13.6.1 PMSM Sensorless Operation

In this configuration the PMSM stator winding currents are driven sinusoidally and the back EMF

waveform is also sinusoidal. Thus all 3 phases are active simultaneously. The rotor position and speed are

determined by the current and calculated voltages respectively. The back EMF voltage is calculated based

on the currents.

2. Configure PMF for center aligned or phase shifted operation.

3. Select correct PMF deadtime insertion based on external FET switches.

4. Enable GDU current sense opamps for measuring the phase currents from 2 external shunts.

5. Map the output pin of each current sense opamp to the ADC input.

1.13.6.2 PMSM Operation With Sine-Cosine Position Sensor

In this configuration the PMSM stator winding currents are driven sinusoidally and the back EMF

waveform is also sinusoidal. Thus all 3 phases are active simultaneously. The back EMF voltage is

calculated based on the currents. The rotor position and speed are determined by a sine/cosine sensor,

which generates sinusoidal sine/cosine signals, indicating the angle of the rotor in relation to sensor

windings. The sensor is supplied by the EVDD1 pin.

1. Configure PMF for complementary mode operation.

2. Configure PMF for center aligned or phase shifted operation.

3. Select correct PMF deadtime insertion based on external FET switches.

4. Enable GDU current sense opamps for measuring the phase currents from external shunts.

5. Map the output pin of each current sense opamp to the ADC input.

1.13.6.3 Dead time Distortion Correction

PMSM motor control applications driven by sinusoidal voltages by default require zero crossing

information of phase currents to determine the point in time to change sign of deadtime compensation

value to be added to duty cycles.

The GDU phase comparator signals are connected internally to the PMF ISx inputs. This allows the dead

time distortion correction to be applied directly based on the phase status.

1. Align rotor to stator field.

2. Await phase comparator status change.

3. Switch to alternate duty cycle register to compensate distortion.

1.13.7 Power Domain Overview (All devices except ZVMC256)

The power domains are illustrate d in Figure 1-17. More detailed information is included in the individual

module descriptions.

Figure 1-17. Power Domain Overview

The system supply voltage VRBATP is a reverse battery protected input voltage. It must be protected

against reverse battery connections and must not be connected directly to the battery voltage (VBAT).

The device supply voltage VSUP provides the input voltage for the internal regulator, VREG_AUTO,

which generates the voltages VDDX, VDD and VDDF. The VDDX domain supplies the device I/O pins,

VDDA supplies the ADC and internal bias current generators. The VDDA and VDDX pins must be

connected at board level, they are not connected directly internally. ESD protection diodes exist between

VDDX and VDDA, therefore forcing a common operating range. The VDD domain supplies the internal

device logic. The VDDF domain supplies sections of the internal Flash NVM circuitry.

The device supports the use of an external PNP to supplement the VDDX supply, for reducing on chip

power dissipation. In this configuration, most of the current flowing from VRBATP to VDDX, flows

through the external PNP. This configuration, using the BCTL pin, can be enabled by register bits

EXTXON and INTXON.

The maximum current that can be sourced by the voltage regulator without the external PNP is specified

as IDDX, for different VSUP ranges, in the electrical parameter appendices. Depending on activity and

external loading, an application current may exceed this specification limit. In such cases the external PNP

configuration must be used.

A supply for an external CANPHY is offered via external device pins BCTLC and VDDC, whereby

BCTLC provides the base current of an external PNP and VDDC is the CANPHY supply (output voltage

of the external PNP). This is only available in the CANPHY package option. This configuration can be

enabled by the register bit EXTCON.

The LINPHY pull-up resistor is internally connected to the HD voltage. This is chosen as opposed to

VSUP to ensure that the LINPHY is not disturbed by the internal VSUP boost circuit. The external

connections for the HD pin must ensure a reverse battery protection.

The ADC register bit VRH_SEL maps the ADC reference VRH to VDDA or to the device pin PAD8.
