dsPIC30F1010/202X
Table 1-1 provides a brief description of device I/O
pinouts for the dsPIC30F1010 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.
