A/D conversion operations are performed continuously until bit 7 (ADCS) of the A/D converter mode register (ADM)
is reset (0) by software.
If a write operation is performed to the analog input channel specification register (ADS) during an A/D conversion
operation, the conversion operation is initialized, and if the ADCS bit is set (1), conversion starts again from the
beginning.
Reset signal generation clears the A/D conversion result register (ADCR, ADCRH) to 0000H or 00H.
