32
WAKE
I
TTL
An external input that brings the processor out of Hibernate mode
when asserted.
33
HIB
O
TTL
An output that indicates the processor is in Hibernate mode.
XOSC0
34
I
Analog Hibernation module oscillator crystal input or an external clock
reference input. Note that this is either a 32.768-kHz crystal or a
32.768-kHz oscillator for the Hibernation module RTC.
GNDX
35
-
Power GND for the Hibernation oscillator. When using a crystal clock
source, this pin should be connected to digital ground along with
the crystal load capacitors. When using an external oscillator, this
pin should be connected to digital ground.
36
XOSC1
O
Analog Hibernation module oscillator crystal output. Leave unconnected
when using a single-ended clock source.
VBAT
37
-
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.
38
RST
I
TTL
System reset input.
39
GND
-
Power Ground reference for logic and I/O pins.
40
OSC0
I
Analog Main oscillator crystal input or an external clock reference input.
41
OSC1
O
Analog Main oscillator crystal output. Leave unconnected when using a
single-ended clock source.
42
VDD
-
Power Positive supply for I/O and some logic.
