Power
The ground reference for the analog circuits (ADC,
Analog Comparators, etc.). These are separated
from GND to minimize the electrical noise contained
on VDD from affecting the analog functions.

VDD
The positive supply 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. VDDA
pins must be supplied with a voltage that meets the
specification in , regardless of system
implementation.
