Table 1-1 provides a brief description of device I/O pin-
outs and the functions that may be multiplexed to a port
pin. Multiple functions may exist on one port pin. When
multiplexing occurs, the peripheral module’s functional
requirements may force an override of the data
direction of the port pin.
