When the execution condition is OFF, MVN(031) is not executed. When the ex-
ecution condition is ON, MVN(031) transfers the complement of the content of S
(specified word or four-digit hexadecimal constant) to D, i.e., for each ON bit in S,
the corresponding bit in D is turned OFF, and for each OFF bit in S, the corre-
sponding bit in D is turned ON.
