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.
