    Hi AAnil,

    To clarify, you would use MII as your MAC Interface here because the collision pin is active default when MII is the MAC.

    You cannot use LED_0 when using this COL function because the two pins are shared.

    This LED pin is configurable via software using the LED Control Registers.

    Simultaneouly, your LINK_ST can be used as an indication of link.

    Regards,

    Aaron
