DP83867E: SGMII

Part Number: DP83867E

I want 4WIREMODE SGMII to work without any MDIO configuration.
Does it work only with LED _ 0 strap setting?
Is there any restriction by not controlling MDIO?
(For example, we cannot enable/disable the autonegotiation function. etc)

    Hello,

    You can use LED_0 to strap the device into SGMII mode, without needing additional MDIO configuration. However MDIO access is highly recommended as a debugging tool and to have the ability to tune the features or performance of the PHY as the system is evaluated. 

    Regards,
