Note 1:
Default peripheral input. Input can be moved to any other pin with the PPS input selection registers. See Register 12-1.
2:
All pin outputs default to PORT latch data. Any pin can be selected as a digital peripheral output with the PPS output selection registers. See Register 12-3.
3:
These peripheral functions are bidirectional. The output pin selections must be the same as the input pin selections.
