B.10 ADC
This section explains the difference in functionality of the conversion complete bit (COCO) in the ADC10
status and control register (ADCSC). Writing ADCSC aborts the current conversion and initiates a new
conversion (if the ADCH[4:0] bits are equal to a value other than all 1s).
COCO — Conversion Complete Bit
COCO is a read-only bit which is set each time a conversion is completed. This bit is cleared whenever
the status and control register is written or whenever the data register is read.
1 = Conversion completed
0 = Conversion not completed
