I don't think Jinx was saying that it was a solution for ALL cases.
Huh? You just said "This is very bad practice but will work".
In this case, the designer gets a bad result because of a bad design.
That's not the fault of the micro at all - it's the designers fault.
The shadow port is unnecessary in this case IF the designed did their job.
Fixing "faulty" code this way (in this case) is just avoiding the cause.
