: Operation result
Description:
1. Logical Double word XOR operation.
2. A logical XOR operation is performed on the bit patterns of the contents of the two source
addresses (
S
2
and
S
1
). The result of the logical DXOR is stored in the destination device (
D
)
3. If operands
S
1
,
S
2
,
D
use index F, only a 16-bit instruction is available.
4. For 16-bit operation please refer to the WXOR instruction.
Program Example:
When X1 = ON, the 32-bit data source = (D11, D10) and (D21, D20) are analyzed and the
operation result of the logical DXOR = is stored in (D41, D40).
