(3) Power fail comparison mode register (PFM)
(4) Power fail comparison threshold value register (PFT)
This register sets the power fail monitoring mode.
It compares the value of the power fail comparison threshold register (PFT) and the value of the A/D
conversion result register (ADCRH).
The PFM register can be read or written in 8-bit or 1-bit units.
This register is cleared to 00H after reset
This register sets the value to be compared in the power fail comparison mode.
The 8-bit data set in the PFT register and the higher 8 bits (ADCRH) of the A/D conversion result register are
compared.
The PFT register can be read or written in 8-bit units.
This register is cleared to 00H after reset.
