Ground reference for logic and I/O pins.
Ground reference for logic and I/O pins.
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.

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. The LDO pin must also be
connected to the VDD25 pins at the board level in
addition to the decoupling capacitor(s).
