what is actually wrong with just using dynamic debug. That lets you easily switch on certain debug statements. I would actually remove all of this and rely completely on dynamic debug instead.

Anyway, there are also BIT(0), BIT(1) etc. choices that would be a lot clearer than 1, 2, 4 etc.

Regards

Marcel
