The SAR register is a 12-bit register that sets voltage tap data whose values from the array match the voltage values
of the analog input pins, 1 bit at a time starting from the most significant bit (MSB).
If data is set in the SAR register all the way to the least significant bit (LSB) (end of A/D conversion), the contents of
the SAR register (conversion results) are held in the A/D conversion result register (ADCR). When all the specified
A/D conversion operations have ended, an A/D conversion end interrupt request signal (INTAD) is generated.
The A/D conversion result is loaded from the successive approximation register to this register each time A/D
conversion is completed, and the ADCR register holds the A/D conversion result in its higher 10 bits (the lower 6 bits
are fixed to 0).
The A/D conversion result is loaded from the successive approximation register to this register each time A/D
conversion is completed, and the ADCRH register stores the higher 8 bits of the A/D conversion result.
This circuit controls the conversion time of an input analog signal that is to be converted into a digital signal, as well
as starting and stopping of the conversion operation. When A/D conversion has been completed, this controller
generates INTAD.
This pin inputs the reference voltage of the A/D converter, the programmable gain amplifier, the power supply pins
and A/D converter of the comparator, and the comparator. When all pins of ports 2, 15, and 8 are used as the analog
port pins, make the potential of AV
and 8 are used as the digital port pins, make AV
The analog signal input to the ANI0 to ANI15 pins is converted into a digital signal, based on the voltage applied
across 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
even when the A/D converter is not used.
