Timer_B3
Timer_B3 is a 16–bit timer/counter with three 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.

Universal Serial Communications Interface (USCI)
The USCI module is used for serial data communication. The USCI module supports synchronous
communication protocols like SPI (3 or 4 pin), I2C and asynchronous communication protocols such as UART,
enhanced UART with automatic baudrate detection (LIN), and IrDA.
USCI_A0 provides support for SPI (3 or 4 pin), UART, enhanced UART, and IrDA.
USCI_B0 provides support for SPI (3 or 4 pin) and I2C.
