5 Understanding Programming
Using Execution Results in N.C. and N.O. Inputs
The Condition Flags will pick up instruction B execution results as shown in the example below even
though the N.C. and N.O. input bits are executed from the same output branch.
Make sure each of the results is picked up once by an OUTPUT instruction to ensure that execution
results for instruction B will be not be picked up.
Example: The following example will move #0200 to D200 if D100 contains #0010 and move #0300
to D300 if D100 does not contain #0010.
