(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. When writing data to the ADA0PFM register in the following modes, stop the A/D
After reset:
value of the ADA0CRnH register 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. If it does not match, however,
the interrupt signal is not generated.
contents of the ADA0CR0H register. 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. If it does not match, however, the INTAD signal is not
generated. Regardless of the comparison result, the scan operation is continued and
the conversion result is stored in the ADA0CRn register until the scan operation is
completed. However, the INTAD signal is not generated after the scan operation has
been completed.
conversion by clearing the AD0M0.ADA0CE bit to 0. After the data is written to the
register, enable the A/D conversion again by setting the ADA0CE bit to 1.
