21 / 100 page  MSP430F5438A-EP www.ti.com SLAS967A – JANUARY 2014 – REVISED JANUARY 2014 Universal Serial Communication Interface (USCI) (Links to User's Guide: UART Mode, SPI Mode, I2C Mode) 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 (Link to User's Guide) 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. Table 9.
