        A data invalid request from the gearbox that occurs after every 32 user_clk cycles

        Check stability of INIT_CLK and GT_REFCLK
        
        Deassert pma_init followed by reset_pb
    - - Assert reset. Wait for a minimum time equal to 128*user_clk's time-period.
        
        Assert pma_init. Keep pma_init and reset asserted for at least one second to prevent
        the transmission of CC characters and ensure that the remote agent detects a hot plug
        event.
        
        Deassert pma_init.
        
        Deassert reset_pb.
