MSP430G2x52 MSP430G2x12 www.ti.com SLAS722G – DECEMBER 2010 – REVISED MAY 2013 SHORT-FORM DESCRIPTION CPU The MSP430 CPU has a 16-bit RISC architecture that is highly transparent to the application. 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.
MSP430G2x52 MSP430G2x12 SLAS722G – DECEMBER 2010 – REVISED MAY 2013 www.ti.com Operating Modes The MSP430 has one active mode and five 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.
MSP430G2x52 MSP430G2x12 www.ti.com SLAS722G – DECEMBER 2010 – REVISED MAY 2013 Interrupt Vector Addresses The interrupt vectors and the power-up starting address are located in the address range 0FFFFh to 0FFC0h. The vector contains the 16-bit address of the appropriate interrupt handler instruction sequence. If the reset vector (located at address 0FFFEh) contains 0FFFFh (for example, if flash is not programmed) the CPU goes into LPM4 immediately after power-up. Table 5.
MSP430G2x52 MSP430G2x12 SLAS722G – DECEMBER 2010 – REVISED MAY 2013 www.ti.com Special Function Registers (SFRs) Most interrupt and module enable bits are collected into the lowest address space. Special function register bits not allocated to a functional purpose are not physically present in the device. Simple software access is provided with this arrangement. Legend rw: rw-0,1: rw-(0,1): Bit can be read and written. Bit can be read and written. It is reset or set by PUC. Bit can be read and written.

MSP430G2x52 MSP430G2x12 www.ti.com SLAS722G – DECEMBER 2010 – REVISED MAY 2013 Main DCO Characteristics • All ranges selected by RSELx overlap with RSELx + 1: RSELx = 0 overlaps RSELx = 1, ..., RSELx = 14 overlaps RSELx = 15. • DCO control bits DCOx have a step size as defined by parameter SDCO. • Modulation control bits MODx select how often fDCO(RSEL,DCO+1) is used within the period of 32 DCOCLK cycles. The frequency fDCO(RSEL,DCO) is used for the remaining cycles.
MSP430G2x52 MSP430G2x12 SLAS722G – DECEMBER 2010 – REVISED MAY 2013 www.ti.com Timer0_A3 Timer0_A3 is a 16-bit timer/counter with three capture/compare registers. Timer0_A3 can support multiple capture/compares, PWM outputs, and interval timing. Timer0_A3 also has extensive interrupt capabilities. Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare registers. Table 11.
