Logic Instructions Section 3-13
Operand Specifications
Description XNRL(613) takes the logical exclusive NOR of data specified in I
1
and I
2
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 0 will be output to the corresponding bit in R, R+1.
When any of them are the same, a 1 will be output to the corresponding
bit in R, R+1.
