48-Pin UQFN
(1,2,3)
= Pins are up to 5V tolerant
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.
4: There is an internal pull-up resistor connected to the TMS pin when the JTAG interface is active. See the
JTAGEN bit field in Table 27-2.
