The RPn/RPIn pins can be used by any remappable peripheral with some limitation. See 

 for available peripherals and for information on limitations.

Every I/O port pin (RAx-RGx) can be used as a Change Notification pin (CNAx-CNGx). See 

 for more information.

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.

There is an internal pull-up resistor connected to the TMS pin when the JTAG interface is active. See the 
JTAGEN bit field in
