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