ORWL(611) takes the logical OR of data specified in I
data and outputs the result to R, R+1.
• When any of the corresponding bits in I
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.

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.
