USART0
The MSP430C13x1 devices have one hardware universal synchronous/asynchronous receive transmit
(USART0) peripheral module that is used for serial data communication. The USART supports synchronous
SPI (3 or 4 pin) and asynchronous UART communication protocols, using double-buffered transmit and receive
channels.
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.
timer_A3
Timer_A3 is a 16-bit timer/counter with three capture/compare registers. Timer_A3 can support multiple
capture/compares, PWM outputs, and interval timing. Timer_A3 also has extensive interrupt capabilities.
Interrupts may be generated from the counter on overflow conditions and from each of the capture/compare
registers.
