Note 1: The RPn/RPIn pins can be used by any remappable peripheral with some limitation. See Section 11.4 “Peripheral
Pin Select (PPS)” for available peripherals and for information on limitations.
2: Every I/O port pin (RAx-RGx) can be used as a Change Notification pin (CNAx-CNGx). See Section 11.0 “I/O
Ports” for more information.
3: The metal pad at the bottom of the device is not connected to any pins and is recommended to be connected to
V
SS externally.
