Note 1: The RPn/RPIn pins can be used by any remappable peripheral with some limitation. See Section 11.4
“Peripheral Pin Select” for available peripherals and for information on limitations.
2: Every I/O port pin (RAx-RGx) can be used as change notification (CNAx-CNGx). See Section 11.0 “I/O
Ports” for more information.
