Description 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.
• When the content of any of the corresponding bits in I
1,
I
1
+1, I
2,
and
I
2
+1are different, a 1 will be output to the corresponding bit it R, R+1. When
any of them are the same, a 0 will be output to the corresponding bit in R,
R+1.
