Preliminary

Table 1-2 provides a brief description of device I/O

pinouts for the dsPIC30F2020 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.
