Compare Enable for Conversion Number
n
(
n
= 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0) of a Sequence
— 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:
1) Write compare value to ATDDR
n
result register
2) Write compare operator with CMPHT[
n
] in ATDCPMHT register
CCF[
n
] in ATDSTAT2 register will flag individual success of any comparison.
0 No automatic compare
