An output that indicates the processor is in
hibernate mode.
Low drop-out regulator output voltage. This pin
requires an external capacitor between the pin and
GND of 1 µF or greater. The LDO pin must also be
connected to the VDD25 pins at the board level in
addition to the decoupling capacitor(s).
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.
Positive supply for most of the logic function,
including the processor core and most peripherals.

The positive supply (3.3 V) for the analog circuits
(ADC, Analog Comparators, etc.). These are
separated from VDD to minimize the electrical noise
contained on VDD from affecting the analog
functions.

An external input that brings the processor out of
hibernate mode when asserted.
