Conversion Complete Flag n (n= 7, 6, 5, 4, 3, 2, 1, 0) (n conversion number, NOT channel number!)— A
conversion complete flag is set at the end of each conversion in a sequence. The flags are associated with the
conversion position in a sequence (and also the result register number). Therefore in non-fifo mode, CCF[4] is
set when the fifth conversion in a sequence is complete and the result is available in result register ATDDR4;
CCF[5] is set when the sixth conversion in a sequence is complete and the result is available in ATDDR5, and
so forth.
If automatic compare of conversion results is enabled (CMPE[n]=1 in ATDCMPE), the conversion complete flag
is only set if comparison with ATDDRn is true. If ACMPIE=1 a compare interrupt will be requested. In this case,
as the ATDDRn result register is used to hold the compare value, the result will not be stored there at the end of
the conversion but is lost.
In case of a concurrent set and clear on CCF[n]: The clearing by method A) will overwrite the set. The clearing
by methods B) or C) or D) will be overwritten by the set.
0 Conversion number n not completed or successfully compared
1 If (CMPE[n]=0): Conversion number n has completed. Result is ready in ATDDRn.
ATD Status Register 2 (ATDSTAT2)
= Unimplemented or Reserved
If (CMPE[n]=1): Compare for conversion result number n with compare value in ATDDRn, using compare
operator CMPGT[n] is true. (No result available in ATDDRn)
A flag CCF[n] is cleared when one of the following occurs:
A) Write to ATDCTL5 (a new conversion sequence is started)
B) If AFFC=0, write “1” to CCF[n]
C) If AFFC=1 and CMPE[n]=0, read of result register ATDDRn
D) If AFFC=1 and CMPE[n]=1, write to result register ATDDRn
