"= CD for Input n" indicates that the Comparator input signals are the same as
the comparison data.
"≠ CD for Input n" indicates that the Comparator input signals are not the
same as the comparison data.
" " indicates that the status is not applicable (the input signals and compari-
×
son data may or may not be the same).
