•
A/D converter mode register (ADM)
•
Analog input channel specification register (ADS)
•
Power fail comparison mode register (PFM)
•
Power fail comparison threshold register (PFT)
•
A/D conversion result register, A/D conversion result register H (ADCR, ADCRH)
(1) A/D converter mode register (ADM)
This register sets the conversion time of the analog input signal to be converted into a digital signal as well as
