timer_B3 (MSP430F23x devices)
Timer_B3 is a 16-bit timer/counter with seven capture/compare registers. Timer_B3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_B3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.

The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols such as SPI (3 or 4 pin) or I²C and asynchronous combination protocols such UART,
enhanced UART with automatic baudrate detection (LIN), and IrDA.
The USCI A module provides support for SPI (3 or 4 pin), UART, enhanced UART, and IrDA.
The USCI B module provides support for SPI (3 or 4 pin) 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.
ADC12
The ADC12 module supports fast, 12-bit analog-to-digital conversions. The module implements a 12-bit SAR
core, sample select control, reference generator, and a 16-word conversion-and-control buffer. The
conversion-and-control buffer allows up to 16 independent ADC samples to be converted and stored without
any CPU intervention.
