4.2.3 Pin Mapping
Using the following hardware connection diagrams, the user can find the required PIM pins and map them with the pins of the PIC24 plug-in-module data sheet to get the actual microcontroller pins. For example, the ATWINC slave select connects to pin 33 of the J9 header on the Explorer 16/32 Development Board, which connects to PIM pin 14, which is the PIC24 device pin 14 (RG9).
