comparison mode register (PFM), or power-fail comparison threshold register (PFT) 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.
A/D conversion operations are performed continuously until bit 7 (ADCS) of the A/D converter mode register (ADM)
If a write operation is performed to one of the ADM, analog input channel specification register (ADS), power-fail
RESET input makes the A/D conversion result register (ADCR) undefined.
