    When you say "run", I am not clear if you are referring to LED showing TX/RX activity or something else. Below is the source supported for LED.

    Below is an example of configuring LED1 for 100Mbit speed

    • Write to PHY register 0x0304 value 0x0008 (Set pin 31 function to LED1)
    • Write to PHY register 0x0460 value 0x0005 (100Mbit speed)
    • Write to PHY register 0x0469 value 0x0004 (Active High polarity)

    Thanks

    David
