Description
HIB
M12
O
OD
An open-drain output with internal pull-up that
indicates the processor is in Hibernate mode.
VBAT
L12
-
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

TTL
An external input that brings the processor out of
Hibernate mode when asserted.
XOSC0

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.
