    Hi Dave,

    What is the device mode being used (OP_MODE = 'xxx')? If RGMII to Copper is being used ('000'), are these default LED functions acceptable:

    If not, the LED functions can be individually adjusted in register 18h.

    For LED_0, set 0x18[3:0] = '1001' for indicating 100/1000BT link up. Similar adjustment is made in [11:8] and [7:4] for LED_2 / LED_1.

    Thank you,

    Evan
