Conversion Complete Flag Bits — 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 CCF flag 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.
Conversion number x not completed
Conversion number x has completed, result ready in ATDDRx
• Write to ATDCTL5 (a new conversion sequence is started)
• If AFFC = 0 and read of ATDSTAT1 followed by read of result register ATDDRx
• If AFFC = 1 and read of result register ATDDRx
