RADCA0 and RADCA1 are special function registers (SFRs) used to read from and write to the Counter A of the
RC-ADC. RADCA0 and RADCA1 are 24-bit binary counters.
[Note]
When A/D conversion starts after data is written, the value that has been written is read during A/D conversion
(RARUN = 1).
When A/D conversion terminates (RARUN = 0), the count value is read.
