                                                           several clocks, depending on the current state of the core.
                                                           Once this bit is cleared software should wait at least 3 PHY

                                                           any operation.
                                                           Typically software reset is used during software development
                                                           and also when you dynamically change the PHY selection bits

                                                           change the PHY, the corresponding clock for the PHY is
