Operand Specifications
Description MCMP(019) compares the contents of the 16 words S
1
through S
1
+15 to the
contents of the 16 words S
2
through S
2
+15, and turns ON the corresponding
bit in word R when the contents are not equal.
The content of S
1
is compared to the content of S
2
, the content of S
1
+1 to the
content of S
2
+1, ..., and the content of S
1
+15 to the content of S
2
+15. Bit n of
R is turned OFF if the content of S
1
+n is equal to the content of S
2
+n; bit n of
R is turned ON if the contents are not equal. If the contents of all 16 pairs of
words are the same, the Equals Flag will turn ON after the instruction has
been executed.
