Ok, thanks a lot to everybody involved for the fast help here! I'm not
quite sure how to interpret the $f800 in the mask register here
(anybody got an idea why the Falcon would return the inverted value
here?), but I think for the most programs, it should be enough to simply
return the value that has been written to the register. What do you
think?
