Internal SGMII Management Registers
Registers 0 through 15 are defined in IEEE 802.3. These registers contain information relating to the operation of the
SGMII PCS sublayer, including the status of both the SGMII Link and the physical Ethernet link (PHY Link).
Additionally, these registers are directly involved in the operation of the SGMII auto negotiation function which
occurs between the XPS_LL_TEMAC and the external PHY device (typically a tri-speed BASE-T PHY).
These registers are accessed via the MII Management interface (see "Using the MII Management to Access Internal
or External PHY Registers" on page 67). These registers are only valid when using the SGMII PHY interface.
