XORW/XORL
Function
Sample program
When the execution condition CIO 0.00 is ON, the logical exclusive OR is taken of corresponding bits in
CIO 151, CIO 150 and D1001, D1000 and the results will be output to corresponding bits in D1201 and
D1200.
XORW
XORW(036) takes the logical exclusive OR of
data specified in I
1
and I
2
and outputs the
result to R.
XORL
XORL(612) takes the logical exclusive OR of
data specified in I
1
and I
2
as double-word data
and outputs the result to R, R+1.
