MOTOROLA
Address:
ADCVIN is the input voltage signal from one of the 15 ADC channels to
the ADC module.
These 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.
