MIXED SIGNAL MICROCONTROLLER
SLAS580D -- OCTOBER 2008 -- REVISED MARCH 2011
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 communication interfaces (USCIs) (USCI_A0, USCI_B0)
The USCI module is used for serial data communication. The USCI module supports synchronous
communication protocols such as SPI (3 pin 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 pin or 4 pin), UART, enhanced UART and IrDA.
USCI_B0 provides support for SPI (3 pin 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.
