3.7.4 ADC Voltage Reference Low Pin (V
The ADC analog portion uses V
to the same voltage potential as V
results. Any noise present on this pin will be reflected and possibly magnified in A/D conversion values.

Function of the ADC status and control register (ADSCR) is described here.

•
In non-interrupt mode (AIEN = 0), COCO is a read-only bit that is set at the end of each conversion.
COCO will stay set until cleared by a read of the ADC data register. Reset clears this bit.
In interrupt mode (AIEN = 1), COCO is a read-only bit that is not set at the end of a conversion. It
always reads as a 0.
1 = Conversion completed (AIEN = 0)
0 = Conversion not completed (AIEN = 0) or CPU interrupt enabled (AIEN = 1)
is the input voltage signal from one of the 24 ADC channels to the ADC module.
