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. Program Counter PC/R0 Stack Pointer SP/R1 SR/CG1/R2 Status Register Constant Generator 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 Instruction Set General-Purpose Register R11 The instruction set consists of 51 instructions with three formats and seven address modes. Each instruction can operate on word and byte data. Table 3 shows examples of the three types of instruction formats; Table 4 shows the address modes. General-Purpose Register R12 General-Purpose Register R13 General-Purpose Register R14 General-Purpose Register R15 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. Table 3.

An interrupt event can wake up the device from any of the five low-power modes, service the request, and restore back to the low-power mode on return from the interrupt program. The following six 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. • Low-power mode 1 (LPM1) – CPU is disabled ACLK and SMCLK remain active. MCLK is disabled. – DCO dc-generator is disabled if DCO not used in active mode. • Low-power mode 2 (LPM2) – CPU is disabled. – MCLK and SMCLK are disabled. – DCO dc-generator remains enabled. – ACLK remains active. • Low-power mode 3 (LPM3) – CPU is disabled. – MCLK and SMCLK are disabled. – DCO dc-generator is disabled. – ACLK remains active. • Low-power mode 4 (LPM4) – CPU is disabled. – ACLK is disabled. – MCLK and SMCLK are disabled. – DCO dc-generator is disabled. – Crystal oscillator is stopped. 8 Submit Documentation Feedback Copyright © 2010–2011, Texas Instruments Incorporated MSP430AFE2x3 MSP430AFE2x2 MSP430AFE2x1 SLAS701A – NOVEMBER 2010 – REVISED MARCH 2011 www.ti.com Interrupt Vector Addresses The interrupt vectors and the power-up starting address are located in the address range of 0FFFFh to 0FFE0h. The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence.

The CPU can perform single-byte and single-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 64 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, or as a group with segments 0 to n. Segments A to D are also called information memory. • Segment A contains calibration data. After reset segment A is protected against programming and erasing. It can be unlocked but care should be taken not to erase this segment if the device-specific calibration data is required.

For complete module descriptions, see the MSP430x2xx Family User's Guide (SLAU144). Oscillator and System Clock The clock system is supported by the basic clock module that includes support for an internal digitally controlled oscillator (DCO), a high-frequency crystal oscillator, and an internal very-low-power low-frequency oscillator (VLO). The basic clock module is designed to meet the requirements of both low system cost and low power consumption. The internal DCO provides a fast turn-on clock source and stabilizes in less than 1 µs. The basic clock module provides the following clock signals: • Auxiliary clock (ACLK), sourced from the VLO • Main clock (MCLK), the system clock used by the CPU • Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules Table 13. DCO Calibration Data (Provided From Factory in Flash Information Memory Segment A) DCO FREQUENCY 8 MHz 12 MHz CALIBRATION REGISTER SIZE ADDRESS CALBC1_8MHZ byte 010FDh CALDCO_8MHZ byte 010FCh CALBC1_12MHZ byte 010FBh CALDCO_12MHZ byte 010FAh Brownout, Supply Voltage Supervisor The brownout circuit is implemented to provide the proper internal reset signal to the device during power on and power off. The supply voltage supervisor (SVS) circuitry detects if 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). The CPU begins code execution after the brownout circuit releases the device reset. However, VCC may not have ramped to VCC(min) at that time. The user must ensure that the default DCO settings are not changed until VCC reaches VCC(min) . If desired, the SVS circuit can be used to determine when VCC reaches VCC(min). Digital I/O There are two I/O ports implemented: 8-bit port P1 and 3-bit port P2. • All individual I/O bits are independently programmable. • Any combination of input, output, and interrupt condition is possible. • Edge-selectable interrupt input capability for all eight bits of port P1 and three bits of port P2. • Read/write access to port-control registers is supported by all instructions. • Each I/O has an individually programmable pullup/pulldown resistor. Because there are only three I/O pins implemented from port P2, bits [5:1] of all port P2 registers read as 0, and write data is ignored. Watchdog Timer (WDT+) The primary function of the WDT+ 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 disabled or configured as an interval timer and can generate interrupts at selected time intervals. 12 Submit Documentation Feedback Copyright © 2010–2011, Texas Instruments Incorporated MSP430AFE2x3 MSP430AFE2x2 MSP430AFE2x1 SLAS701A – NOVEMBER 2010 – REVISED MARCH 2011 www.ti.com Timer_A3 Timer_A3 is a 16-bit timer/counter with three capture/compare registers.

The USART0 module supports synchronous SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered transmit and receive channels. The maximum operational frequency for the USART0 module is 8 MHz. Hardware Multiplier The multiplication operation is supported by a dedicated peripheral module. The module performs 16x16, 16x8, 8x16, and 8x8 bit operations. The module is capable of supporting signed and unsigned multiplication as well as signed and unsigned multiply and accumulate operations. The result of an operation can be accessed immediately after the operands have been loaded into the peripheral registers. No additional clock cycles are required. SD24_A The SD24_A module integrates up to three independent 24-bit sigma-delta A/D converters. Each channel is designed with fully differential analog input pair and programmable gain amplifier input stage. In addition to external analog inputs, an internal VCC sense and temperature sensor are also available.

(b) Design a good ground plane around the oscillator pins. (c) Prevent crosstalk from other clock or data lines into oscillator pins XT2IN and XT2OUT. (d) Avoid running PCB traces underneath or adjacent to the XT2IN and XT2OUT pins. (e) Use assembly materials and praxis to avoid any parasitic load on the oscillator XT2IN and XT2OUT pins. (f) If conformal coating is used, ensure that it does not induce capacitive/resistive leakage between the oscillator pins. Includes parasitic bond and package capacitance (approximately 2 pF per pin). Because 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, and frequencies in between might set the flag. Measured with logic-level input frequency, but also applies to operation with crystals.

When activated, a fuse check current, ITF , of 1 mA at 3 V or 2.5 mA at 5 V can flow from the TEST pin to ground if the fuse is not burned. Care must be taken to avoid accidentally activating the fuse check mode and increasing overall system power consumption. When the TEST pin is again taken low after a test or programming session, the fuse check mode and sense currents are terminated. Activation of the fuse check mode occurs with the first negative edge on the TMS pin after power up or if TMS is being held low during power up. The second positive edge on the TMS pin deactivates the fuse check mode. After deactivation, the fuse check mode remains inactive until another POR occurs. After each POR, the fuse check mode has the potential to be activated. The fuse check current flow only when the fuse check mode is active and the TMS pin is in a low state (see Figure 17). Therefore, the additional current flow can be prevented by holding the TMS pin high (default condition). Time TMS Goes Low After POR TMS ITF ITEST Figure 17. Fuse Check Mode Current NOTE The CODE and RAM data protection is ensured if the JTAG fuse is blown.
