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, 0) is cleared
when one of the following occurs:
0 Conversion number x not completed
1 Conversion number x has completed, result ready in ATDDRx

A) Write to ATDCTL5 (a new conversion sequence is started)
B) If AFFC = 0 and read of ATDSTAT1 followed by read of result register ATDDRx
C) If AFFC = 1 and read of result register ATDDRx
