    1.
    Data based on design simulation and/or characterisation results, not tested in production.
    2.
    Depends on fPCLK. For example, if fPCLK=8MHz, then tPCLK = 1/fPLCLK =125ns and tv(MO) = 255ns.
    3.
    Min. time is the minimum time to drive the output and the max. time is the maximum time to validate the data.
    4.
    Min time is the minimun time to invalidate the output and the max time is the maximum time to put the data in Hi-Z.
