(5) A/D conversion result registers n, nH (ADA0CRn, ADA0CRnH)
The ADA0CRn and ADA0CRnH registers store the A/D conversion results.
These registers are read-only, in 16-bit or 8-bit units. However, specify the ADA0CRn register for 16-bit access and
the ADA0CRnH register for 8-bit access. The 10 bits of the conversion result are read from the higher 10 bits of the
ADA0CRn register, and 0 is read from the lower 6 bits. The higher 8 bits of the conversion result are read from the
ADA0CRnH register.
Caution Accessing the ADA0CRn and ADA0CRnH registers is prohibited in the following statuses. For
Caution A write operation to the ADA0M0 and ADA0S registers may cause the contents of the

be read if a sequence other than the above is used.
