Choosing the configuration requires the review of all
PPSs and their pin assignments, especially those that
will not be used in the application. In all cases, unused
pin-selectable peripherals should be disabled com-
pletely. Unused peripherals should have their inputs
assigned to an unused RPn pin function. I/O pins with
unused RPn functions should be configured with the
NULL peripheral output.
The assignment of a peripheral to a particular pin does
not automatically perform any other configuration of the
pin’s I/O circuitry. In theory, this means adding a pin-
selectable output to a pin may mean inadvertently
driving an existing peripheral input when the output is
driven. Users must be familiar with the behavior of
other fixed peripherals that share a remappable pin and
know when to enable or disable them. To be safe, fixed
digital peripherals that share the same pin should be
disabled when not in use.
Along these lines, configuring a remappable pin for a
specific peripheral does not automatically turn that
feature on. The peripheral must be specifically config-
ured for operation and enabled, as if it were tied to a
fixed pin. Where this happens in the application code
(immediately following device Reset and peripheral
configuration or inside the main application routine)
depends on the peripheral and its use in the
application.
A final consideration is that the PPS functions neither
override analog inputs nor reconfigure pins with analog
functions for digital I/O. If a pin is configured as an
analog input on a device Reset, it must be explicitly
reconfigured as a digital I/O when used with a PPS.
Example 10-7 provides a configuration for bidirectional
communication with flow control using EUSART2. The
following input and output functions are used:
Input Function RX2
Output Function TX2
EXAMPLE 10-7:

INPUT AND OUTPUT
FUNCTIONS
Note:
If the Configuration bit, IOL1WAY = 1,
once the IOLOCK bit is set, it cannot be
cleared, preventing any future RP register
changes. The IOLOCK bit is cleared back
to ‘0’ on any device Reset.
