Description
 S
1
source data device 1
S
2
source data device 2
D: operation result
 This instruction conducts logical XOR operation of S
1
and S
2
and stores the result in D.
 If the bits in S
1
and S
2
are the same, the corresponding bit of the operation result in D will be
“0”;
if the bits in S
1
and S
2
are different, the corresponding bit of the operation result in D will be “1”.
Example
 When X0 = ON,16-bit D0 and D2 perform XWOR, logical XOR operation, and the result will be
stored in D4.

When X1 = ON, 32-bit (D11, D10) and (D21, D20) perform XDOR, logical XOR operation, and
the result will be stored in (D41, D40).
