OD
An open-drain output with internal pull-up that
indicates the processor is in Hibernate mode.
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.
TTL
An external input that brings the processor out of
Hibernate mode when asserted.
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.
Analog
OD
Hibernation module oscillator crystal output. Leave
unconnected when using a single-ended clock
source.
