ADAnPFM - ADC power-fail compare mode register
The ADAnPFM register is an 8-bit register that sets the power-fail compare
mode.
This register can be read or written in 8-bit or 1-bit units.
Reset input clears this register to 00H.

1. In the select mode, the 8-bit data set to the ADAnPFT register is compared
with the value of the ADAnCRmH register specified by the ADAnS register. If
the result matches the condition specified by the ADAnPFC bit, the
conversion result is stored in the ADAnCRm register and the INTAD signal is
generated. If it does not match, however, the interrupt signal is not
generated.
2. In the scan mode, the 8-bit data set to the ADAnPFT register is compared
with the contents of the ADAnCR0H register. If the result matches the
condition specified by the ADAnPFC bit, the conversion result is stored in
the ADAnCR0 register and the INTAD signal is generated. If it does not
match, however, the INTAD signal is not generated. Regardless of the
comparison result, the scan operation is continued and the conversion result
is stored in the ADAnCRm register until the scan operation is completed.
However, the INTAD signal is not generated after the scan operation has
been completed.
