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.
