Positive supply for most of the logic function,
including the processor core and most
peripherals.

Power
Positive supply for most of the logic function,
including the processor core and most
peripherals.
Power
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.

OD
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 4.19-MHz crystal or a
32.768-kHz oscillator for the Hibernation
Module RTC. See the CLKSEL bit in the
HIBCTL register.
