Pin TypePin NumberPin NameFunction
An output that indicates the processor is in
Hibernate mode.
ODO51HIB
Hibernate
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.
Power-55VBAT
An external input that brings the processor out of
Hibernate mode when asserted.
TTLI50WAKE
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.
AnalogI52XOSC0
Hibernation module oscillator crystal output. Leave
unconnected when using a single-ended clock
source.
