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.

USCI
The universal serial communication interface (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 like 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.
