The RPn pins can be used by remappable peripherals. See
Table 1
for the available peripherals and
Section 11.3 “Peripheral Pin
Select”
for restrictions.
Every I/O port pin (RAx-RCx) can be used as a change notification pin (CNAx-CNCx). See
Section 11.0 “I/O Ports”
for more information.
Shaded pins are 5V tolerant.
