Figure 10-5. A/D Converter Basic Operation
A/D conversion operations are performed continuously until bit 7 (ADCS3) of the ADM is reset (0) by software.
If a write to ADM3 or ADS3 is performed during an A/D conversion operation, the conversion operation is initialized,
and if the ADCS3 bit is set (1), conversion starts again from the beginning.
After reset input, the value of ADCR3 is undefined.
