Operation error
• There is no operation error in the WXNR(P) or DXNR(P) instruction.
Program example
• The following program compares the bit patterns of the 16-bit data located from X30 to X3F with the bit patterns of the 16-
bit data at D99 when XC is ON, and stores the number of identical bit patterns at D7.
