One-shot scan mode
In this mode, the results of converting the voltages of the analog input pins
sequentially selected from the ANI0 pin to the pin specified by the ADAnS
register are stored, and the set value of the ADAnCR0H register of channel 0 is
compared with the value of the ADAnPFT register. If the result of power-fail
comparison matches the condition set by the ADAnPFC bit of the ADAnPFM
register, the conversion result is stored in the ADAnCR0 register, and the
INTAD signal is generated. If it does not match, the conversion result is stored
in the ADAnCR0 register, and the INTAD signal is not generated.
After the result of the first conversion has been stored in the ADAnCR0
register, the results of sequentially converting the voltages on the analog input
pins up to the pin specified by the ADAnS register are continuously stored.
After completion of conversion, A/D conversion is stopped. The 1st conversion
result after A/D conversion has been ignored, because it is not good.
