(3) A/D conversion result register, A/D conversion result register H (ADCR, ADCRH)
The ADCR and ADCRH registers store the A/D conversion results.
These registers are read-only in 16-bit or 8-bit units. However, specify the ADCR register for 16-bit access,
and the ADCRH register for 8-bit access. In the ADCR register, the 10 bits of conversion results are read in
the higher 10 bits and 0 is read in the lower 6 bits. In the ADCRH register, the higher 8 bits of the conversion
results are read.
Reset makes these registers undefined.
After reset: Undefined R Address: FFFFF204H
