I had a bit of confusion trying to understand how the remappable pins work on my PIC24FJ256GB110 MCU. Peripherals like the UARTS require a pin assignment before they can be used. So a solid understanding of how these work is essential. I went through the PIC's datasheet and the device's header file and created a 17 page summary PDF which I hope will help others understand and use the remappable pin feature. Referred to as peripheral pin selection (PPS).

The document can be seen HERE.

There isn't anything unique in this document as I borrowed heavily from the Microchip data sheet and their device header. What might be helpful are my explanations and having all the tables/macros in one place.
