5.4 Supporting Interrupts for PIC® Devices

This section demonstrates how to enable interrupts in the application code for PIC® devices.

Description: It is always recommended to avoid using interrupts in the bootloader code when possible to avoid errors due to complexity, but user applications can freely support interrupts if they follow a few required steps. This section demonstrates several interrupt variations for the different PIC® devices that the 8-Bit MDFU Client supports. Select the section below that corresponds to the interrupt format required:
