The ADA0PFM 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.
In continuous select mode the conversion result of ADC channel ANIn,
selected by ADA0S, is observed.
In continuous scan mode the conversion result of ADC channel ANI0 is
observed.
For further details, refer to “Power-fail compare mode“ on page 785.
