    I had tried implementation with the pinout as desired and it did nor work. Hence I had posted here if there was a workaround.
    I did try the interface planner after your suggestion and got the errors there too.

    If there was a way to to make it work, as I had described in the original post. please let me know.

    Best,

    Bharat
