WXOR, WXORP: 7 steps
DWXOR, DWXORP: 9 steps
Operands:
S
1
: Source data device 1
S
2
: Source data device 2
D
: Operation result
Explanations:
1. WXOR conducts logical XOR operation of
S
1
and
S
2
in 16-bit mode and stores the result in
D
2. When WXOR is used as 16-bit instruction, Z device cannot be adopted; when WXOR is used as 32-bit
instruction, V device cannot be adopted.
Program Example 1:
When X0 = ON, the 16-bit data source D0 and D2 are analyzed and the operation result of the logical XOR is stored
in D4.

Program Example 2:
When X1 = ON, the 32-bit (D11, D10) and (D21, D20) will perform DWXOR logical XOR operation, and the result will
be stored in (D41, D40).
