Logic Instructions
Section 3-13
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.

Flags
Precautions
When XORL(612) is executed, the Error Flag will turn OFF.
If as a result of the exclusive OR, the content of R, R+1 is 00000000 hex, the
Equals Flag will turn ON.
If as a result of the exclusive OR, the leftmost bit of R+1 is 1, the Negative
Flag will turn ON.
Examples
When the execution condition CIO 00000000 is ON, the logical exclusive OR
is taken of corresponding bits in CIO 0901, CIO 0900 and D01001, D01000
and the results will be output to corresponding bits in D01201 and D01200.
