Table 1-1 provides a brief description of device I/O

pinouts 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.
