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.

Low drop-out regulator output voltage. This pin
requires an external capacitor between the pin and
GND of 1 µF or greater. When the on-chip LDO is
used to provide power to the logic, the LDO pin
must also be connected to the VDD25 pins at the
board level in addition to the decoupling
capacitor(s).
