(10) A/D converter mode register (ADM)
(11) Analog input channel specification register (ADS)
(12) Power-fail comparison mode register (PFM)
(13) Power-fail comparison threshold register (PFT)
The result of A/D conversion is loaded from the successive approximation register (SAR) to this register each
time A/D conversion is completed, and the ADCR register holds the result of A/D conversion in its higher 10 bits
(the lower 6 bits are fixed to 0).
When A/D conversion has been completed or when the power-fail detection function is used, this controller
compares the result of A/D conversion (value of the ADCR register) and the value of the power-fail comparison
threshold register (PFT). It generates the interrupt INTAD only if a specified comparison condition is satisfied as
a result.
This pin inputs an analog power/reference voltage to the A/D converter. Always use this pin at the same potential
as that of the V
The signal input to ANI0 to ANI3 is converted into a digital signal, based on the voltage applied across AV
AV
This is the ground potential pin of the A/D converter. Always use this pin at the same potential as that of the V
pin even when the A/D converter is not used.
This register is used to set the conversion time of the analog input signal to be converted, and to start or stop the
conversion operation.
This register is used to specify the port that inputs the analog voltage to be converted into a digital signal.
This register is used to set the power-fail monitor mode.
This register is used to set the threshold value that is to be compared with the value of the A/D conversion result
register (ADCR).
