All operations, other than program-flow instructions, are performed as register operations in conjunction with seven addressing modes for source operand and four addressing modes for destination operand. The CPU is integrated with 16 registers that provide reduced instruction execution time. The register-to-register operation execution time is one cycle of the CPU clock. Four of the registers, R0 to R3, are dedicated as program counter, stack pointer, status register, and constant generator, respectively. The remaining registers are general-purpose registers. Peripherals are connected to the CPU using data, address, and control buses, and can be handled with all instructions. The instruction set consists of the original 51 instructions with three formats and seven address modes and additional instructions for the expanded address range. Each instruction can operate on word and byte data. 12 Submit Documentation Feedback Program Counter PC/R0 Stack Pointer SP/R1 Status Register Constant Generator SR/CG1/R2 CG2/R3 General-Purpose Register R4 General-Purpose Register R5 General-Purpose Register R6 General-Purpose Register R7 General-Purpose Register R8 General-Purpose Register R9 General-Purpose Register R10 General-Purpose Register R11 General-Purpose Register R12 General-Purpose Register R13 General-Purpose Register R14 General-Purpose Register R15 Copyright (c) 2010, Texas Instruments Incorporated MSP430F543xA, MSP430F541xA www.ti.com SLAS655B - JANUARY 2010 - REVISED OCTOBER 2010 Operating Modes The MSP430 has one active mode and six software selectable low-power modes of operation. An interrupt event can wake up the device from any of the low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program. The following seven operating modes can be configured by software: * Active mode (AM) - All clocks are active * Low-power mode 0 (LPM0) - CPU is disabled - ACLK and SMCLK remain active, MCLK is disabled - FLL loop control remains active * Low-power mode 1 (LPM1) - CPU is disabled - FLL loop control is disabled - ACLK and SMCLK remain active, MCLK is disabled * Low-power mode 2 (LPM2) - CPU is disabled - MCLK and FLL loop control and DCOCLK are disabled - DCO's dc-generator remains enabled - ACLK remains active * Low-power mode 3 (LPM3) - CPU is disabled - MCLK, FLL loop control, and DCOCLK are disabled - DCO's dc generator is disabled - ACLK remains active * Low-power mode 4 (LPM4) - CPU is disabled - ACLK is disabled - MCLK, FLL loop control, and DCOCLK are disabled - DCO's dc generator is disabled - Crystal oscillator is stopped - Complete data retention * Low-power mode 4.5 (LPM4.5) - Internal regulator disabled - No data retention - Wakeup from RST, digital I/O Copyright (c) 2010, Texas Instruments Incorporated Submit Documentation Feedback 13 MSP430F543xA, MSP430F541xA SLAS655B - JANUARY 2010 - REVISED OCTOBER 2010 www.ti.com Interrupt Vector Addresses The interrupt vectors and the power-up start address are located in the address range 0FFFFh to 0FF80h.

The CPU can perform single-byte, single-word, and long-word writes to the flash memory. Features of the flash memory include: * Flash memory has n segments of main memory and four segments of information memory (A to D) of 128 bytes each. Each segment in main memory is 512 bytes in size. * Segments 0 to n may be erased in one step, or each segment may be individually erased. * Segments A to D can be erased individually. Segments A to D are also called information memory. * Segment A can be locked separately. RAM Memory The RAM memory is made up of n sectors. Each sector can be completely powered down to save leakage, however all data is lost. Features of the RAM memory include: * RAM memory has n sectors. The size of a sector can be found in Memory Organization. * Each sector 0 to n can be complete disabled; however, data retention is lost. * Each sector 0 to n automatically enters low-power retention mode when possible. * For devices that contain USB memory, the USB memory can be used as normal RAM if USB is not required.

P8 contains seven individual I/O ports. P9 through P11 do not exist. Port PJ contains four individual I/O ports, common to all devices. * All individual I/O bits are independently programmable. * Any combination of input, output, and interrupt conditions is possible. * Pullup or pulldown on all ports is programmable. * Drive strength on all ports is programmable. * Edge-selectable interrupt and LPM4.5 wakeup input capability is available for all bits of ports P1 and P2. * Read/write access to port-control registers is supported by all instructions. * Ports can be accessed byte-wise (P1 through P11) or word-wise in pairs (PA through PF). Oscillator and System Clock The clock system in the MSP430x5xx family of devices is supported by the Unified Clock System (UCS) module that includes support for a 32-kHz watch crystal oscillator (XT1 LF mode), an internal very-low-power low-frequency oscillator (VLO), an internal trimmed low-frequency oscillator (REFO), an integrated internal digitally controlled oscillator (DCO), and a high-frequency crystal oscillator (XT1 HF mode or XT2). The UCS module is designed to meet the requirements of both low system cost and low power consumption. The UCS module features digital frequency locked loop (FLL) hardware that, in conjunction with a digital modulator, stabilizes the DCO frequency to a programmable multiple of the selected FLL reference frequency. The internal DCO provides a fast turn-on clock source and stabilizes in less than 5 s. The UCS module provides the following clock signals: * Auxiliary clock (ACLK), sourced from a 32-kHz watch crystal, a high-frequency crystal, the internal low-frequency oscillator (VLO), the trimmed low-frequency oscillator (REFO), or the internal digitally controlled oscillator DCO. * Main clock (MCLK), the system clock used by the CPU. MCLK can be sourced by same sources made available to ACLK. * Sub-Main clock (SMCLK), the subsystem clock used by the peripheral modules. SMCLK can be sourced by same sources made available to ACLK. * ACLK/n, the buffered output of ACLK, ACLK/2, ACLK/4, ACLK/8, ACLK/16, ACLK/32. Power Management Module (PMM) The PMM includes an integrated voltage regulator that supplies the core voltage to the device and contains programmable output levels to provide for power optimization. The PMM also includes supply voltage supervisor (SVS) and supply voltage monitoring (SVM) circuitry, as well as brownout protection. The brownout circuit is implemented to provide the proper internal reset signal to the device during power-on and power-off. The SVS/SVM circuitry detects if the supply voltage drops below a user-selectable level and supports both supply voltage supervision (the device is automatically reset) and supply voltage monitoring (SVM, the device is not automatically reset). SVS and SVM circuitry is available on the primary supply and core supply. Hardware Multiplier The multiplication operation is supported by a dedicated peripheral module. The module performs operations with 32-bit, 24-bit, 16-bit, and 8-bit operands. The module is capable of supporting signed and unsigned multiplication as well as signed and unsigned multiply and accumulate operations. 18 Submit Documentation Feedback Copyright (c) 2010, Texas Instruments Incorporated MSP430F543xA, MSP430F541xA www.ti.com SLAS655B - JANUARY 2010 - REVISED OCTOBER 2010 Real-Time Clock (RTC_A) The RTC_A module can be used as a general-purpose 32-bit counter (counter mode) or as an integrated real-time clock (RTC) (calendar mode). In counter mode, the RTC_A also includes two independent 8-bit timers that can be cascaded to form a 16-bit timer/counter. Both timers can be read and written by software. Calendar mode integrates an internal calendar which compensates for months with less than 31 days and includes leap year correction. The RTC_A also supports flexible alarm functions and offset-calibration hardware. Watchdog Timer (WDT_A) The primary function of the watchdog timer (WDT_A) module is to perform a controlled system restart after a software problem occurs. If the selected time interval expires, a system reset is generated. If the watchdog function is not needed in an application, the module can be configured as an interval timer and can generate interrupts at selected time intervals.

For example, the DMA controller can be used to move data from the ADC12_A conversion memory to RAM. Using the DMA controller can increase the throughput of peripheral modules. The DMA controller reduces system power consumption by allowing the CPU to remain in sleep mode, without having to awaken to move data to or from a peripheral. Table 9.

(a) Keep the trace between the device and the crystal as short as possible. (b) Design a good ground plane around the oscillator pins. (c) Prevent crosstalk from other clock or data lines into oscillator pins XIN and XOUT. (d) Avoid running PCB traces underneath or adjacent to the XIN and XOUT pins. (e) Use assembly materials and praxis to avoid any parasitic load on the oscillator XIN and XOUT pins. (f) If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins. When XT1BYPASS is set, XT1 circuits are automatically powered down. Input signal is a digital square wave with parametrics defined in the Schmitt-trigger Inputs section of this datasheet. Maximum frequency of operation of the entire device cannot be exceeded. Oscillation allowance is based on a safety factor of 5 for recommended crystals. The oscillation allowance is a function of the XT1DRIVEx settings and the effective load. In general, comparable oscillator allowance can be achieved based on the following guidelines, but should be evaluated based on the actual crystal selected for the application: (a) For XT1DRIVEx = 0, CL,ef f 6 pF. (b) For XT1DRIVEx = 1, 6 pF CL,ef f 9 pF. (c) For XT1DRIVEx = 2, 6 pF CL,ef f 10 pF. (d) For XT1DRIVEx = 3, CL,ef f 6 pF. Includes parasitic bond and package capacitance (approximately 2 pF per pin). Since the PCB adds additional capacitance, it is recommended to verify the correct load by measuring the ACLK frequency. For a correct setup, the effective load capacitance should always match the specification of the used crystal. Requires external capacitors at both terminals. Values are specified by crystal manufacturers. Frequencies below the MIN specification set the fault flag. Frequencies above the MAX specification do not set the fault flag. Frequencies in between might set the flag. Measured with logic-level input frequency but also applies to operation with crystals.

Please refer to the REF module parametric, IREF+, regarding the current consumption of the temperature sensor. The temperature sensor offset can be as much as 20C. A single-point calibration is recommended in order to minimize the offset error of the built-in temperature sensor. The TLV structure contains calibration values for 30C 3C and 85C 3C for each of the available reference voltage levels. The sensor voltage can be computed as VSENSE = TCSENSOR x (Temperature,C) + VSENSOR, where TCSENSOR and VSENSOR can be computed from the calibration values for higher accuracy. See also the MSP430x5xx Family User's Guide (SLAU208). The typical equivalent impedance of the sensor is 51 k. The sample time required includes the sensor-on time tSENSOR(on). The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.

The input capacitance, Ci, is also the dynamic load for an external reference during conversion. The dynamic impedance of the reference supply should follow the recommendations on analog-source impedance to allow the charge to settle for 12-bit accuracy. The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced accuracy requirements. The accuracy limits the maximum negative external reference voltage. Higher reference voltage levels may be applied with reduced accuracy requirements. The accuracy limits minimum external differential reference voltage. Lower differential reference voltage levels may be applied with reduced accuracy requirements. Two decoupling capacitors, 10F and 100nF, should be connected to VREF to decouple the dynamic current required for an external reference source if it is used for the ADC12_A.

The ADC uses two internal buffers, one smaller and one larger for driving the VREF+ terminal. When REFOUT = 1, the reference is available at the VREF+ terminal, as well as, used as the reference for the conversion and utilizes the larger buffer. When REFOUT = 0, the reference is only used as the reference for the conversion and utilizes the smaller buffer. The internal reference current is supplied via terminal AVCC. Consumption is independent of the ADC12ON control bit, unless a conversion is active. REFOUT = 0 represents the current contribution of the smaller buffer. REFOUT = 1 represents the current contribution of the larger buffer without external load. The temperature sensor is provided by the REF module. Its current is supplied via terminal AVCC and is equivalent to IREF+ with REFON =1 and REFOUT = 0.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.

Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
