MOTOROLA Introduction 1-1
Chapter 1
Introduction
The 56F801EVM is used to demonstrate the abilities of the 56F801 and to provide a
hardware tool allowing the development of applications that use the 56F801.
The 56F801EVM is an evaluation module board that includes a 56F801 part, peripheral
expansion connectors, external memory and a JTAG interface. The expansion connectors
are for signal monitoring and user feature expandability.
The 56F801EVM is designed for the following purposes:
• Allowing new users to become familiar with the features of the 56800 architecture.
The tools and examples provided with the 56F801EVM facilitate evaluation of the
feature set and the benefits of the family.
• Serving as a platform for real-time software development. The tool suite enables
the user to develop and simulate routines, download the software to on-chip or
on-board RAM, run it, and debug it using a debugger via the JTAG/OnCETM port.
The breakpoint features of the OnCE port enable the user to easily specify complex
break conditions and to execute user-developed software at full-speed, until the
break conditions are satisfied. The ability to examine and modify all user
accessible registers, memory and peripherals through the OnCE port greatly
facilitates the task of the developer.
• Serving as a platform for hardware development. The hardware platform enables
the user to connect external hardware peripherals. The on-board peripherals can be
disabled, providing the user with the ability to reassign any and all of the device’s
peripherals. The OnCE port's unobtrusive design means that all of the memory on
the board and on the chip are available to the user.

1.3 56F801EVM Connections
An interconnection diagram is shown in Figure 1-3 for connecting the PC and the external
+12V DC power supply to the 56F801EVM board.
Perform the following steps to connect the 56F801EVM cables:
1. Connect the parallel extension cable to the Parallel port of the host computer.
2. Connect the other end of the parallel extension cable to P2, shown in Figure 1-3,
on the 56F801EVM board. This provides the connection which allows the host
computer to control the board.
3. Make sure that the external +12V DC, 4.0A power supply is not plugged into a
120V AC power source.
4. Connect the 2.1mm output power plug from the external power supply into P1,
shown in Figure 1-3, on the 56F801EVM board.
5. Apply power to the external power supply. The green Power-On LED, LED8, will
illuminate when power is correctly applied.

2-4 56F801EVM Hardware User’s Manual MOTOROLA
2.2 RS-232 Serial Communications
The 56F801EVM provides an RS-232 interface by the use of an RS-232 level converter,
(Maxim MAX3245EEAI, designated as U2). Refer to the RS-232 schematic diagram in
Figure 2-3. The RS-232 level converter transitions the SCI UART’s +3.3V signal levels
to RS-232 compatible signal levels and connects to the host’s serial port via connector P4.
Flow control is not provided, but could be implemented using uncommitted GPIO signals.
The pinout of connector P4 is listed in Table 2-1. The RS-232 level converter/transceiver
can be disabled by placing a jumper at JG6.

2.3 Clock Source
The 56F801EVM uses an 8.00MHz crystal, Y1, connected to its External Crystal Inputs,
EXTAL and XTAL. The 56F801 uses its internal PLL to multiply the input frequency by
10, to achieve its 80MHz maximum operating frequency. An external oscillator source can
be connected to the device by using the oscillator bypass connector, JG7 and JG8; see
Figure 2-2.
Figure 2-2. Block Diagram of the Clock Interface
2.4 Debug LEDs
One on-board Light-Emitting Diode (LED) is provided to allow real-time debugging for
user programs. This LED allows the programmer to monitor program execution without
having to stop the program during debugging; refer to Figure 2-3. This user LED,
designated LED7, is controlled by the MOSI signal. Setting the MOSI to a Logic One
value will turn on the LED.

2.5 Debug Support
The 56F801EVM provides an on-board Parallel JTAG Host Target Interface and a JTAG
interface connector for external Target Interface support. Two interface connectors are
provided to support each of these debugging approaches. These two connectors are
designated the JTAG connector and the Host Parallel Interface Connector.
2.5.1 JTAG Connector
The JTAG connector on the 56F801EVM allows the connection of an external Host
Target Interface for downloading programs and working with the 56F801’s registers. This
connector is used to communicate with an external Host Target Interface which passes
information and data back and forth with a host processor running a debugger program.
Table 2-2 shows the pin-out for this connector.
When this connector is used with an external Host Target Interface, the parallel JTAG
interface should be disabled by placing a jumper in jumper block JG5. Reference
Table 2-3 for this jumper’s selection options.

2.12 Motor Protection Logic
The 56F801EVM contains a UNI-3 connector that interfaces with various motor drive
boards. The device can sense error conditions generated by the motor power stage boards
via signals on the UNI-3 connector. The motor driver board’s Motor Supply DC Bus
Voltage, Current and Motor Phase Currents are sensed on the power stage board. The
conditioned signals are transferred to the board via the UNI-3 connector. These analog
input signals are compared to a limit set by trimpots. If the input analog signals are greater
than the limit set by the trimpot, a controller digital voltage-compatible +3.3V DC fault
signal is generated.

Quadrature Encoder/Hall-Effect Interface
MOTOROLA Technical Summary 2-17
2.13 Back-EMF and Motor Phase Current Sensing
The UNI-3 connector supplies Back-EMF and Motor Phase Current signals from the three
phases of a motor attached to a motor drive unit. The Back-EMF signals on the UNI-3
connector are derived from a resistor divider network contained in the motor drive unit.
These resistors divide down the attached motor’s Back-EMF voltages to a 0 to +3.3V
level. The Motor Phase Current signals are derived from current sense resistors. Both of
these signal groups are then routed to a group of header pins, JG4, that allow the end user
to select which signal group the device’s A/D will monitor; reference Figure 2-11.
Figure 2-11. Back-EMF or Motor Phase Current Sense Signals
2.14 Quadrature Encoder/Hall-Effect Interface
The 56F801EVM board contains a Quadrature Encoder/Hall-Effect interface connected to
the device’s Timer D port signals, TD1 and TD2. The circuit is designed to accept +3.0V
to +5.0V encoder or Hall-Effect sensor inputs. Input noise filtering is supplied on the input
path for the Quadrature Encoder/Hall-Effect interface. Figure 2-12 shows the encoder
interface.

2.15 Zero-Crossing Detection
An attached UNI-3 motor drive board contains logic that can send out pulses when the
phase voltage of an attached 3-phase motor drops to zero. The motor drive board circuits
generate a 0 to +5.0V DC pulse via voltage comparators. The resulting pulse signals are
sent to a set of jumper blocks shared with the Encoder/Hall-Effect interface. The jumper
blocks allow the selection of Zero-Crossing signals or Quadrature Encoder/Hall-Effect
signals. When in operation, the hybrid controller will only monitor one set of signals,
Encoder/Hall-Effect or Zero-Crossing. Figure 2-12 contains the Zero-Crossing and
