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-toregister 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 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's 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's dc-generator remains enabled – ACLK remains active • Low-power mode 3 (LPM3) – CPU is disabled – MCLK and SMCLK are disabled – DCO's dc-generator is disabled – ACLK remains active • Low-power mode 4 (LPM4) – CPU is disabled – ACLK is disabled – MCLK and SMCLK are disabled – DCO's dc-generator is disabled – Crystal oscillator is stopped Copyright © 2012, Texas Instruments Incorporated Submit Documentation Feedback 5 MSP430G2230-EP SLAS863 – AUGUST 2012 www.ti.com Interrupt Vector Addresses The interrupt vectors and the power-up starting address are located in the address range of 0x0FFFF to 0x0FFC0. The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence. If the reset vector (located at address 0x0FFFE) contains 0x0FFFF (for example, flash is not programmed) the CPU goes into LPM4 immediately after power-up. Table 5.

Multiple source flags (non)-maskable: the individual interrupt-enable bit can disable an interrupt event, but the general interrupt enable cannot. Interrupt flags are located in the module. All eight interrupt flags P1IFG.0 to P1IFG.7 are implemented while four are connected to pins. The interrupt vectors at addresses 0xFFDE to 0xFFC0 are not used in this device and can be used for regular program code if necessary.

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. 8 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated MSP430G2230-EP www.ti.com SLAS863 – AUGUST 2012 Peripherals Peripherals are connected to the CPU through data, address, and control buses and can be handled using all instructions. 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 a 32768-Hz watch crystal oscillator, an internal very-low-power low-frequency oscillator and an internal digitally-controlled oscillator (DCO). 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 either from a 32768-Hz watch crystal or the internal LF (VLOCLK) oscillator. • Main clock (MCLK), the system clock used by the CPU. • Sub-Main clock (SMCLK), the sub-system clock used by the peripheral modules. NOTE The LFXT1 oscillator is not available. LFXT1Sx bits of the BCSCTL3 register should be configured to use VLOCLK (see the MSP430x2xx Family User's Guide (SLAU144)). Table 9.

Digital I/O There are four pins of one 8-bit I/O port implemented—port P1: • 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 the four bits of port P1. • Read/write access to port-control registers is supported by all instructions. • Each I/O has an individually programmable pullup/pulldown resistor.

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. Timer_A2 Timer_A2 is a 16-bit timer/counter with two capture/compare registers. Timer_A2 can support multiple capture/compares, PWM outputs, and interval timing. Timer_A2 also has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers. Table 10.

The accuracy limits the minimum positive external reference voltage. Lower reference voltage levels may be applied with reduced accuracy requirements. Under this condition the external reference is internally buffered. The reference buffer is active and requires the reference buffer supply current IREFB. The current consumption can be limited to the sample and conversion period with REBURST = 1. The accuracy limits the maximum negative external reference voltage.

When REFON = 1, ISENSOR is included in IREF+. When REFON = 0, ISENSOR applies during conversion of the temperature sensor input (INCH = 0Ah). The following formula can be used to calculate the temperature sensor output voltage: VSensor,typ = TCSensor (273 + T [°C] ) + VOffset,sensor [mV] or VSensor,typ = TCSensor T [°C] + VSensor(TA = 0°C) [mV] The typical equivalent impedance of the sensor is 51 kΩ. The sample time required includes the sensor-on time tSENSOR(on). No additional current is needed. The VMID is used during sampling. The on-time tVMID(on) is included in the sampling time tVMID(sample); no additional on time is needed.
