(4) A/D conversion result registers (ADCR0 to ADCR7, ADCR0H to ADCR7H)
The ADCRn register is a 10-bit register holding the A/D conversion results. There are eight 10-bit registers.
These registers are read-only in 16-bit or 8-bit units. During 16-bit access, the ADCRn register is specified,
and during higher 8-bit access, the ADCRnH register is specified (n = 0 to 7).
When reading the 10-bit data of the A/D conversion results from the ADCRn register during 16-bit access,
only the lower 10 bits are valid and the higher 6 bits are always read as 0.
