     * @group:       	4.14.4 SERIAL GIGABIT MEDIA INDEPENDENT INTERFACE (SGMII) (PORT 7)
     *
     * @description:	The port 7 MAC has a Serial Gigabit Media Independent Interface (SGMII) for interfacing to an external 10/100/1000
     * 					BASE-T PHY that supports the SGMII MAC/PHY interface, or to another device with an SGMII interface. This interface
     * 					also has a SerDes mode for interfacing to 1000BASE-X fiber optic modules or to other modules such as 1000BASE-T
     * 					which do not support SGMII.
     * 					The interface has one receive differential pair and one transmit differential pair for sending and receiving data and con-
     * 					trol at a serial bit rate of 1.25 Gbaud. The SGMII block recovers the clock from the incoming data. Therefore, a separate
     * 					input SGMII clock is not needed. Likewise, no output SGMII clock is provided, with the expectation that the connected
     * 					device will also recover the clock from the receive data.
     * 					SGMII uses auto-negotiation to establish the MAC - PHY connection. The PHY-side device is sometimes referred to as
     * 					the master, and the MAC-side device is referred to as the slave. The PHY-side device relays the following information
     * 					about the 10/100/1000 BASE-T link to the MAC-side device:
     * 					• Speed
     * 					• Duplex
     * 					• Link up/down status
     * 					The switch’s SGMII interface defaults to MAC-side mode, with auto-negotiation enabled. The mode can be changed to
     * 					PHY-side for connection to a MAC-side device. There is also the option to disable auto-negotiation. If auto-negotiation
     * 					is disabled, it must also be disabled in both devices. Do not confuse “auto-negotiation” across the SGMII interface with
     * 					auto-negotiation performed between the PHY and its far-end link partner. When the SGMII speed and duplex can be
     * 					fixed, as when connected to another switch or a processor, auto-negotiation is optional.
     * 					10/100/1000 BASE-T PHYs with SGMII interfaces may be discrete devices or may be housed in SFP modules. Note,
     * 					however, that not all SFP modules support SGMII.
     * 					In SerDes mode, this port uses 1000BASE-X “auto-negotiation”. Unlike the SGMII interface where one device acts as
     * 					a PHY and one acts as a MAC, the SerDes interface is symmetrical between the two connected devices. Besides being
     * 					compatible with 1000BASE-X fiber modules, it can also interface to a copper 1000BASE-T PHY or module that uses
     * 					1000BASE-X auto-negotiation instead of SGMII, and is fixed at 1 Gbps and full duplex. When a PHY is connected to
     * 					this port, the auto-negotiation is between the switch and the PHY, and this local PHY is known as the link partner. When
     * 					a 1000BASE-X fiber module is connected to this port, the auto-negotiation is between the PHY and the distant link part-
     * 					ner. The fiber module does not participate in the auto-negotiation.
     * 					The switch cannot auto-detect the type of SFP module it is attached to, but a management processor can access the
     * 					SGMII registers and determine whether the received auto-negotiation codeword corresponds to an SGMII device or a
     * 					SerDes mode device.
     * 					AC coupling should be used on the SGMII differential pairs. AC coupling capacitors are included in SFP modules. The
     * 					SGMII port has internal termination resistors, which eliminates the need for external termination.
     * 					SGMII registers are accessed indirectly via the Port SGMII Address Register and Port SGMII Data Register. Additional
     * 					information on SGMII registers is provided in Section 5.5, "SGMII Registers (Indirect)," on page 228.
     * 					Additional information about this interface and its use is provided in an application note.
