9.10.7 Enhanced Universal Serial Communication Interface (eUSCI_A0, eUSCI_B0)

The eUSCI modules are used for serial data communications. The eUSCI_A module supports either UART or SPI communications. The eUSCI_B module supports either SPI or I2C communications. Additionally, eUSCI_A supports automatic baud-rate detection and IrDA. The eUSCI_A and eUSCI_B are connected either from P1 port or P2 port, it can be selected from the USCIA0RMP or USCIBxRMP bits of SYSCFG2 and SYSCFG3. Table 9-11 lists the pin configurations that are required for each eUSCI mode.
