Address:
ADCVIN is the input voltage signal from one of the 6 ADC channels to
the ADC module.
Three I/O registers control and monitor ADC operation:
The following paragraphs describe the function of the ADC status and
control register.
COCO — Conversions Complete Bit

•
When the AIEN bit is a logic 0, the COCO is a read-only bit which is
set each time a conversion is completed. This bit is cleared whenever
the ADC status and control register is written or whenever the ADC
data register is read. Reset clears this bit.
When the AIEN bit is a logic 1 (CPU interrupt enabled), the COCO is
a read-only bit, and will always be logic 0 when read.
