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