3.7.3.11 UART2 Pin Muxing
The UART2 module can operate as either a UART or IrDA/CIR interface. The UART2 pin muxing options
are shown in Table 3-36 through Table 3-38. When UART operation is selected, UART2CTL must be set
to either ‘00’ for UART with flow control or ‘01’ for UART without flow control signals. When IrDA/CIR
operation is selected, UART2CTL must be set to ‘10’ to use the IrDA/CIR signals. If UART2 is unused,
then setting UART2CTL = 11 muxes GPIO function onto all the pins. The UART2 pin functions may be
overridden based on the settings of TSPIMUX, CRGMUX, and TSSOMUX.
