The eUSCI module is used for serial data communication. The eUSCI 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.
The eUSCI_An module supports for SPI (3- or 4-pin), UART, enhanced UART, or IrDA.
The eUSCI_Bn module supports for SPI (3- or 4-pin) or I2C.
Three eUSCI_A and one eUSCI_B modules are implemented in MSP430F67xx devices.
