11.4.3.1 Input Mapping
The inputs of the Peripheral Pin Select 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 11-8
through Register 11-26).
Each register contains two sets of 6-bit fields, with each
set associated with one of the pin-selectable peripher-
als. Programming a given peripheral’s bit field, with an
appropriate 6-bit value, maps the RPn/RPIn pin with
that value to that peripheral. For any given device, the
valid range of values for any of the bit fields corre-
sponds to the maximum number of Peripheral Pin
Selections supported by the device.
