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 baud-rate 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.
ADC10
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.
