(4) A/D conversion result registers 00 to 07 and 10 to 17 (ADCR00 to ADCR07, ADCR10 to ADCR17)

The ADCR0n and ADCR1n registers are 10-bit registers that hold the results of A/D conversions (n = 0 to 7).

One A/D converter is equipped with eight 10-bit registers for 8 channels, and A/D converters 0 and 1 together

have sixteen 10-bit registers.

These registers are read-only, in 16-bit units.

When reading 10 bits of data of an A/D conversion result from an ADCR0n or ADCR1n register, only the

lower 10 bits are valid and the higher 6 bits are always read as 0.
