Peripheral pin select configuration enables peripheral
set selection and placement on a wide range of I/O
pins. By increasing the pinout options available on a
particular device, programmers can better tailor the
microcontroller to their entire application, rather than
trimming the application to fit the device.
The peripheral pin select configuration feature
operates over a fixed subset of digital I/O pins.
Programmers can independently map the input and/or
output of most digital peripherals to any one of these
I/O pins. Peripheral pin select is performed in
software, and generally does not require the device to
be reprogrammed. Hardware safeguards are included
that prevent accidental or spurious changes to the
peripheral mapping, once it has been established.
11.6.1
The peripheral pin select feature is used with a range
of up to 26 pins. The number of available pins depends
on the particular device and its pin count. Pins that
support the peripheral pin select feature include the
designation “RPn” in their full pin designation, where
“RP” designates a remappable peripheral and “n” is the
remappable pin number.
11.6.2
Peripheral pin select features are controlled through
two sets of special function registers: one to map
peripheral inputs, and one to map outputs. Because
they are separately controlled, a particular peripheral’s
input and output (if the peripheral has both) can be
placed on any selectable function pin without
constraint.
The association of a peripheral to a peripheral select-
able pin is handled in two different ways, depending on
whether an input or output is being mapped.

11.6.2.1
The inputs of the peripheral pin select options are
mapped on the basis of the peripheral. A control
register associated with a peripheral dictates the pin it
is mapped to. The RPINRx registers are used to
configure peripheral input mapping (see Register 11-1
through Register 11-14). Each register contains sets of
5-bit fields, with each set associated with one of the
remappable
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
bit field corresponds to the maximum number of
peripheral pin selections supported by the device.
Figure 11-2 illustrates remappable pin selection for
U1RX input.

For input mapping only, the Peripheral Pin
Select (PPS) functionality does not have
priority over the TRISx settings. Therefore,
when configuring the RPx pin for input, the
corresponding bit in the TRISx register
must also be configured for input (i.e., set
to ‘1’).
