Function
Compares 16 consecutive words with another 16
consecutive words and turns ON the corresponding bit
in the result word where the contents of the words are
not equal.
Comparison
Compares the source data to the contents of 16 words
and turns ON the corresponding bit in the result word
when the contents are equal.
Comparison
Compares the source data to 16 ranges (defined by 16
lower limits and 16 upper limits) and turns ON the
corresponding bit in the result word when the source data
is within the range.

Compares the source data to up to 256 ranges (defined by
upper and lower limits) and turns ON the corresponding bit in
the result word when the source data is within a range.

Compares the 16-bit unsigned binary value in CD (word con-
tents or constant) to the range defined by LL and UL and out-
puts the results to the Arithmetic Flags in the Auxiliary Area.
