The ADC module has four channels that are shared with port B pins.
Refer to
voltages referenced here.
The ADC analog portion uses V
pin.
Due to pin limitations, the V

internally connected to V
ADCVIN is the input voltage signal from one of the four ADC channels to
the ADC module.
These I/O registers control and monitor ADC operation:
