6.1 Overview

General purpose I/O (GPIO) pins allow the PIC32CX-BZ3 devices to monitor and control other devices. To add flexibility and functionality, some pins are multiplexed with alternate function(s). These functions depend on which peripheral features are on the device. In general, when a peripheral is functioning, do not use that pin as a general purpose I/O pin. For more details on pin multiplexing, see GPIO Pins/PPS Functions from Related Links. There are default priorities for each GPIO pin as well. For details on priorities, see Function Priority for Device Pins from Related Links.
