Conversion Counter — These 4 read-only bits are the binary value of the conversion counter. The conversion
counter points to the result register that will receive the result of the current conversion. E.g. CC3=0, CC2=1,
CC1=1, CC0=0 indicates that the result of the current conversion will be in ATD Result Register 6. If in non-FIFO
mode (FIFO=0) the conversion counter is initialized to zero at the begin and end of the conversion sequence. If
in FIFO mode (FIFO=1) the register counter is not initialized. The conversion counters wraps around when its
maximum value is reached.
Aborting a conversion or starting a new conversion clears the conversion counter even if FIFO=1.
Compare Enable for Conversion Number n (n= 7, 6, 5, 4, 3, 2, 1, 0) of a Sequence (n conversion number,
NOT channel number!) — These bits enable automatic compare of conversion results individually for
conversions of a sequence. The sense of each comparison is determined by the CMPHT[n] bit in the ATDCMPHT
register.
For each conversion number with CMPE[n]=1 do the following:
CCF[n] in ATDSTAT2 register will flag individual success of any comparison.
0 No automatic compare
1 Automatic compare of results for conversion n of a sequence is enabled.
ATD Compare Enable Register (ATDCMPE)
= Unimplemented or Reserved
1) Write compare value to ATDDRn result register
2) Write compare operator with CMPHT[n] in ATDCPMHT register
