Interrupts
In the continuous conversion mode, the ADC Data Register will be filled
with new data after each conversion. Data from the previous conversion
will be overwritten whether that data has been read or not. Conversions
will continue until the ADCO bit is cleared. The COCO bit is set after the
first conversion and will stay set for the next several conversions until the
next write of the ADC status and control register or the next read of the
ADC data register.
The conversion process is monotonic and has no missing codes.
Interrupts
When the AIEN bit is set, the ADC module is capable of generating CPU
interrupts after each ADC conversion. A CPU interrupt is generated if the
COCO bit is at logic zero. The COCO bit is not used as a conversion
complete flag when interrupts are enabled.
