The controller compares the result of A/D conversion (the value of the ADA0CRnH register) with the value of
the ADA0PFT register when A/D conversion is completed or when the power-fail detection function is used, and
generates the INTAD signal only when the specified comparison condition is satisfied.
This register specifies the hardware trigger mode.
This register specifies the pin to which the analog voltage to be converted is input.
This register controls power-fail monitoring.
The ADA0PFT register sets the threshold value that is compared with the value of A/D conversion result
register nH (ADA0CRnH). The 8-bit data set to the ADA0PFT register is compared with the higher 8 bits of
the A/D conversion result register (ADA0CRnH).
This is the pin used to input the reference voltage of the A/D converter. Always make the potential of this pin
the same as that of the V
