I just wanted to mention the tables you refer (D4-23 and D4-25) give
Magic_N for a larger scope as they deal with any lookup level while we
only care about the entry level for BADDR. So I was a little bit
confused when reading the explanation but that's not a big deal.
Ah, ok. I will try to clarify it.
