(four-to one-cycle-previous data and new data). 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'.
