A/D conversion operations are performed continuously until bit 7 (ADCS0) of A/D converter mode register 0 (ADM0)
is reset (0) by software.
If a write operation is performed to ADM0 or analog input channel specification register 0 (ADS0) during an A/D
conversion operation, the conversion operation is initialized, and if the ADCS0 bit is set (1), conversion starts again
from the beginning.
RESET input sets the A/D conversion result register 0 (ADCR0) to 00H.
The completion of A/D conversion can be confirmed using the A/D conversion completion interrupt request flag
(ADIF0).
