Universal Serial Communication Interface (USCI)
The USCI modules are used for serial data communication. The USCI module supports synchronous
communication protocols such as SPI (3 or 4 pin) and I²C, and asynchronous communication protocols such as
UART, enhanced UART with automatic baudrate detection, and IrDA. Each USCI module contains two portions,
A and B.
The USCI_An module provides support for SPI (3 pin or 4 pin), UART, enhanced UART, or IrDA.
The USCI_Bn module provides support for SPI (3 pin or 4 pin) or I2C.
The MSP430F5438A, MSP430F5436A, and MSP430F5419A include four complete USCI modules (n = 0 to 3).
The MSP430F5437A, MSP430F5435A, and MSP430F5418A include two complete USCI modules (n = 0 to 1).
TA0
TA0 is a 16-bit timer/counter (Timer_A type) with five capture/compare registers. It can support multiple
capture/compares, PWM outputs, and interval timing. It also has extensive interrupt capabilities. Interrupts may
be generated from the counter on overflow conditions and from each of the capture/compare registers.
