(3) One-shot select mode
(4) One-shot scan mode
A/D
In this mode, the result of converting the voltage of the analog input pin specified by the ADA0S register is
compared with the set value of the ADA0PFT register. If the result of power-fail comparison matches the
condition set by the ADA0PFC bit, the conversion result is stored in the ADA0CRn register, and the INTAD
signal is generated. If it does not match, the conversion result is stored in the ADA0CRn register, and the
INTAD signal is not generated. Conversion is stopped after it has been completed.
In this mode, the results of converting the voltages of the analog input pins sequentially selected from the ANI0
pin to the pin specified by the ADA0S register are stored, and the set value of the ADA0CR0H register of
channel 0 is compared with the set value of the ADA0PFT register. If the result of power-fail comparison
matches the condition set by the ADA0PFC bit, the conversion result is stored in the ADA0CR0 register and the
INTAD signal is generated. If it does not match, the conversion result is stored in the ADA0CR0 register, and
the INTAD0 signal is not generated. After the result of the first conversion has been stored in the ADA0CR0
register, the results of converting the signals on the analog input pins specified by the ADA0S register are
sequentially stored. The conversion is stopped after it has been completed.
