6 Signal Description

The following tables provide details on signal names classified by peripherals.

Note: IOSET Configurations – The PIC32CK device family has multiple peripheral instances, mapped to different I/O locations. Each peripheral I/O location is called IOSET and for a given peripheral, signals from different IOSET cannot be mixed.

For a given peripheral with two pads, PAD0 and PAD1:

Valid: PAD0 and PAD1 in the same IOSETn
Invalid: PAD0 in IOSETx and PAD1 in IOSETy

Note: Bolded pins are only available on PIC32CK1012 variant devices.
