Table 1-3 provides a brief description of device I/O pin-
outs for the dsPIC30F2023 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.
