Description
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.
GPIO port B bit 4
Analog comparator 0 negative input
GPIO port B bit 6
Analog comparator 0 positive input
Analog comparator 0 output
GPIO port B bit 7
