SGMII mode initialization sequence is very similar to TBI mode initialization. Additional initialization is
required for the SerDes. An example of SGMII mode initialization sequence is shown in
14-234
Initialize SerDes to select SGMII. The initialization sequence should be prepended with SerDes initialization.
SGMII Interface Support
SGMII mode utilizes the internal TBI PHY. The internal TBI PHY only
auto-negotiates at 1 Gbps. However, 10 Mbps and 100 Mbps speeds are
supported in SGMII mode. It is recommended that the external PHY inform
the MAC if the desired link speed is not 1 Gbps. Software can perform MII
management cycles to determine the external PHY link speed and program
ECNTRL and MACCFG2 accordingly.
