ADAnCRm, ADAnCRmH - ADC conversion result registers
The ADAnCRm and ADAnCRmH registers store the A/D conversion results.
These registers are read-only, in 16-bit or 8-bit units. However, specify the
ADAnCRm register for 16-bit access and the ADAnCRmH register for 8-bit
access. The 10 bits of the conversion result are read from the higher 10 bits of
the ADAnCRm register, and 0 is read from the lower 6 bits. The higher 8 bits of
the conversion result are read from the ADAnCRmH register.

When writing to the ADAnM0-ADAnM2, ADAnS, ADAnPFM and the ADAnPFT
register the contents of the ADAnCRm registers might become undefined.
Therefore, after the conversion operation ends read the conversion result
before writing to any of the above registers.
Moreover, when external/timer trigger is used, the content of the ADAnCRm
register must be read before the following external/timer trigger is accepted.
