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.

(1) Only one pin-oscillator must be enabled at a time.
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.
Comparator_A+
The primary function of the Comparator_A+module is to support precision slope analog-to-digital conversions,
battery-voltage supervision, and monitoring of external analog signals.
ADC10 (MSP430G2x52 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.
