I'd like to share P0..P7 between xmm driver and an LCD drawing driver...

Can this be done easily?

    I just answered this in your other thread.

    Thanks. Maybe I shouldn't have started a new thread, but I think this is a different question.
    Anyway, your answer was to use HUBTEXT. I'll give that a shot...

    In addition, you'll have to make sure that the other hardware lets go of the pins before leaving the HUBTEXT function otherwise the program will crash on the next cache miss.
