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 fourteen channels, eleven channels are shared
with port A and port C I/O pins; two channels are analog pins, OPIN1 and
OPIN2, that are shared with the analog module; and one channel,
OPOUT, from the analog module.
