Pin Number
Pin Name
Pin Type Buffer Type^a Description
XOSC0
52
I
Analog Hibernation module oscillator crystal input or an external clock
reference input. Note that this is either a 4.194304-MHz crystal or
a 32.768-kHz oscillator for the Hibernation module RTC. See the
CLKSEL bit in the HIBCTL register.
53
XOSC1
O
Analog Hibernation module oscillator crystal output. Leave unconnected
when using a single-ended clock source.
54
GND
-
Power Ground reference for logic and I/O pins.
VBAT
55
-
Power Power source for the Hibernation module. It is normally connected
to the positive terminal of a battery and serves as the battery
backup/Hibernation module power-source supply.
56
VDD
-
Power Positive supply for I/O and some logic.
57
GND
-
Power Ground reference for logic and I/O pins.
