Description
Analog-to-digital converter input 1.
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.
No connect. Leave the pin electrically
unconnected/isolated.
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.
