NOTE:
The ADC module is inactive after the execution of a STOP instruction.
Any pending conversion is aborted. ADC conversions resume when the
MCU exits stop mode. Allow one conversion cycle to stabilize the analog
circuitry before attempting a new ADC conversion after exiting stop
mode.
The ADC module has eight channels that are shared with port A I/O pins,
PTA7/KBA7/AD7–PTA0/KBA0/AD0.
The ADC analog portion uses V

ADCVIN is the input voltage signal from one of the eight ADC channels
to the ADC module.
