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.

USI

The universal serial interface (USI) module is used for serial data communication and provides the basic

hardware for synchronous communication protocols like SPI and I2C.

ADC10 (MSP430G2x31 only)

The ADC10 module supports fast, 10-bit analog-to-digital conversions. The module implements a 10-bit SAR

core, sample select control, reference generator and data transfer controller, or DTC, for automatic conversion

result handling, allowing ADC samples to be converted and stored without any CPU intervention.
