Conversion Complete Flag x (x = 7, 6, 5, 4, 3, 2, 1, 0) — A conversion complete flag is set at the end of each
conversion in a conversion sequence. The flags are associated with the conversion position in a sequence (and
also the result register number). Therefore, CCF0 is set when the first conversion in a sequence is complete and
the result is available in result register ATDDR0; CCF1 is set when the second conversion in a sequence is
complete and the result is available in ATDDR1, and so forth. A flag CCFx (x = 7, 6, 5, 4, 3, 2,1, 70) is cleared
when one of the following occurs:
In case of a concurrent set and clear on CCFx: The clearing by method A) will overwrite the set. The clearing by
methods B) or C) will be overwritten by the set.
