>(what a stupid thing to leave out!!!) So how does this work?
Yes, you are absolutely correct. I am wondering if my 65816 memories are
clouding my memory of the 6502. In any case, it was a really dumb thing not
to include an immediate bit instruction. But yes, simply...
bit CXP0FB
is all that is required. D6 and D7 now occupy the V and N flags
respectively.
