Any idea why is IE=1 and OE=1 marked as "disallowed"?

Yeah, that was a bit of a mystery but after reverse engineering the IO there is no reason that you can't have IE and OE at the same time.

And we used them that way in TinyTapeout ( IE is always `1` and then we toggle `OE` as needed ) and they worked fine AFAICT.
