Logical AND and logical OR between the data are carried out to obtain AND result X and OR result Z, logical operations between the previous result In-1 and AND result X is carried out to obtain a result Y, and logical AND between the result Y and the OR result Z is carried out. A bit "A" whose AND result X is "1" is set again to "1", and a bit B whose OR result Z is "0" is set again to "0".
