result
A/D conversion is successively executed until bit 7 (ADCS) of A/D converter mode register 1 (ADM1) is reset to 0
by software.
If ADM1 and the analog input channel specification register (ADS) are written during A/D conversion, the
conversion is initialized. If ADCS is set to 1 at this time, conversion is started from the beginning.
RESET input sets the A/D conversion result register (ADCR) to 0000H.
