A/D conversion operations are performed continuously until bit 7 (ADCS1) of the A/D converter mode register
(ADM1) is reset (to 0) by software.
If a write operation to the ADM1 and analog input channel specification register (ADS1) is performed during an
A/D conversion operation, the conversion operation is initialized, and if the ADCS1 bit is set (to 1), conversion starts
again from the beginning.
RESET input clears the A/D conversion result register (ADCR1) to 00H.
