14.5.5 Power-fail compare mode
the specified voltage is judged, and if the condition specified by the ADA0PFC bit is satisfied, the A/D conversion end
interrupt request signal (INTAD) is generated.
shot select mode, and one-shot scan mode.

In this mode, whether the input analog signal voltage is the specified voltage or higher or whether it is lower than
• When the ADA0PFM.ADA0PFE bit is 0, the INTAD signal is generated each time A/D conversion is completed at
• When the ADA0PFE bit is 1 and when the ADA0PFM.ADA0PFC bit is 0, the value of the ADA0CRnH register is
• When the ADA0PFE bit is 1 and when the ADA0PFC bit is 1, the value of the ADA0CRnH register is compared
In the power-fail compare mode, four modes are available: continuous select mode, continuous scan mode, one-

compared with the value of the ADA0PFT register when conversion is completed, and the INTAD signal is
generated only if ADA0CRnH ≥ ADA0PFT.
with the value of the ADA0PFT register when conversion is completed, and the INTAD signal is generated only if
ADA0CRnH < ADA0PFT.
Remark
• Continuous/one-shot select mode: After the fist A/D conversion is complete
• Continuous/one-shot scan mode:
n = 0 to 11
