That sounds reasonable to me. I have no preference as to what gets written
into the other slot, since it's undefined by the spec what should happen.
I'd even be ok with just enabling the slot and not doing the
assignment--that will make the slot contain garbage, of course, but that
would fulfill the spec too.
