Power-fail monitor function (conversion result compare function)
A/D conversion is repeated at a resolution of 10 bits for an analog signal that is input to a channel selected
from ANI0 to ANI11.
This function is used to detect a drop in the battery voltage. The result of A/D conversion (the value of the
ADA0CRnH register) is compared with the value of the ADA0PFT register, and the INTAD signal is generated
only when the comparison condition specified by the ADA0PFM register is satisfied (n = 0 to 11).
