Interesting. Thank you Philippe! I can see how the loop might be faster despite the storage reference.

This message was sent from outside your organization. Hi João, I'm glad you liked the macro. In my implementation I use shift in a loop before execute. This is much faster than memory access through IC instruction. Even in the worst case when it shifts seven times it's faster than IC. That's why I didn't use it. You can test in a loop to be certain.
