• One-shot scan mode
The following functions are provided as trigger modes.
• Software trigger mode
• External trigger mode (external, 1)

Power-fail monitor function (conversion result compare function)
An analog input channel is selected from ANI0 to ANI11, and an A/D conversion operation is repeated at a
resolution of 10 bits. Each time A/D conversion has been completed, an interrupt request signal (INTAD) is
generated.
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 a specified comparison condition is satisfied (n = 0 to 11).
