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 lower 12 bits (the higher 4 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 an analog power to the A/D converter. When one or more of the pins of ports 2 and 15 are used as
the digital port pins, make 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.
