-
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.

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

I
Analog 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.
