Logic Instructions Section 3-13
Description ORWL(611) takes the logical OR of data specified in I
1
and I
2
as double-word
data and outputs the result to R, R+1.
• When any of the corresponding bits in I
1,
I
1
+1, I
2,
and I
2
+1are 1, a 1 will
be output to the corresponding bit it R+1. When any of them are 0, a 0 will
be output to the corresponding bit in R+1.
(I

Flags
Precautions When ORWL(611) is executed, the Error Flag will turn OFF.
If as a result of the OR, the content of R, R+1 is 00000000 hex, the Equals
Flag will turn ON.
If as a result of the OR, the leftmost bit of R+1 is 1, the Negative Flag will turn
ON.
