1. A system comprising:
a physical interface for a PCI express (PCIe) PIPE5 controller including a plurality of media access control (MAC) registers;
a PIPE4 device; and
a converter including a first interface coupled to the PIPE5 controller through a message bus interface, a second interface coupled to the PIPE4 device through a PCIe link and a plurality of physical (PHY) registers, wherein, when a first message bus interface signal is received from the PIPE5 controller, the first interface finds a target PHY register among the plurality of PHY registers based on the first message bus interface signal, and the second interface generates a first link interface signal associated with the target PHY register and outputs the first link interface signal to the PIPE4 device, and
wherein, when a second link interface signal is received from the PIPE4 device, the first interface finds a target MAC register among the plurality of MAC registers based on the second link interface signal and outputs a second message bus interface signal to write to the target MAC register based on the second link interface signal.
