Logic Instructions Section 3-12
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.
Examples When the execution condition CIO 0.00 is ON, the logical OR will be taken of
corresponding bits in CIO 1001, CIO 1000 and CIO 2001, CIO 2000 and the
results will be output to corresponding bits in D501 and D500.
3-12-5 EXCLUSIVE OR: XORW(036)
Purpose Takes the logical exclusive OR of corresponding bits in single words of word
data and/or constants.
