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.
If the AIEN bit is a logic 1, the COCO is a read/write bit which selects
the CPU to service the ADC interrupt request. Reset clears this bit.
