Description
HIB
51
O
OD
An open-drain output with internal pull-up that
indicates the processor is in Hibernate mode.
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.
Hibernate
WAKE
50
I
TTL
An external input that brings the processor out of
Hibernate mode when asserted.
XOSC0

I
Analog Hibernation module oscillator crystal input or an
external clock reference input. Note that this is
either a crystal or a 32.768-kHz oscillator for the
Hibernation module RTC.
XOSC1
