10.7.3.1 Input Mapping
The inputs of the PPS options are mapped on the basis
of the peripheral; that is, a control register associated
with a peripheral dictates the pin it will be mapped to. The
RPINRx registers are used to configure peripheral input
mapping (see Register 10-7 through Register 10-21).
Each register contains a 5-bit field which is associated
with one of the pin-selectable peripherals. Programming
a given peripheral’s bit field with an appropriate 5-bit
value maps the RPn pin with that value to that peripheral.
For any given device, the valid range of values for any of
the bit fields corresponds to the maximum number of
peripheral pin selections supported by the device.
