Table 1-1 provides a brief description of the device I/O
pinout and the functions that are multiplexed to the port
pins on the dsPIC30F5016. 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.
