3.3.2 UART Routing

This LaunchPad allows for one of two sets of pins to be used for the SCIA UART routed to the virtual COM port of the XDS110. By default, GPIO28 (SCIA_RX) and GPIO29 (SCIA_TX) are routed to the virtual COM port and not available on the BoosterPack connector. Alternately, GPIO23 (SCIB_RX) and GPIO40 (SCIB_TX) can be routed to the virtual COM port. When UART functionality is not needed at the virtual COM port, the GPIOs can be routed to the BoosterPack connectors for BoosterPack standard functions.

The routing destination of these signal pairs are selected using the on-board switch S2, as described in Table 3-4.
