(6) Power-fail compare mode register (ADA0PFM)
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.
Reset sets this register to 00H.
Cautions 1. In the select mode, the 8-bit data set to the ADA0PFT register is compared with the
ADA0PFM
2. In the scan mode, the 8-bit data set to the ADA0PFT register is compared with the
3. In the following modes, write data to the ADA0PFM register while A/D conversion is
After reset:
conversion result of the channel specified by the ADA0S register. If the result matches
the condition specified by the ADA0PFC bit, the conversion result is stored in the
ADA0CRn register and the INTAD signal is generated.
conversion result is stored in the ADA0CR0 register and the INTAD signal is not
generated.
conversion result of channel 0. If the result matches the condition specified by the
ADA0PFC bit, the conversion result is stored in the ADA0CR0 register and the INTAD
signal is generated.
ADA0CR0 register but the INTAD signal is not generated. Also, regardless of the
comparison result, scanning continues after comparison and the conversion result
continue to be stored in the ADA0CRn register until scanning ends. However, the
INTAD signal is not generated after the scanning has finished.
