Chapter 7
Digital Input and Output
Abstract
This chapter covers digital inputs and outputs on the PIC32, including open-drain outputs and change-notification digital inputs that generate interrupts when the input transitions from low to high or vice-versa. The chapter describes the special function registers (SFRs) that control the digital input and output peripherals. Sample code is given that implements a change notification interrupt and that configures some pins as digital inputs, some as analog inputs, some as digital outputs, and some as open-drain digital outputs.
