LED Function Definitions when LED_FUN[1:0] = 11b
When
When
The LED pins are push-pull drivers.
The LED polarity does not depend upon the
pin is driven high when the function signal is high, and is driven low when the function signal is low.
The input buffers and pull-ups are disabled on the shared GPIO/LED pins.
TX_EN Port 0 - Non-stretched TX_EN signal from the Switch Fabric to the external MII pins.
Note: Link indication does not affect this function.
RX_DV Port 0 - Non-stretched RX_DV signal from the external MII pins to the Switch Fabric.
Note: Link indication does not affect this function.
TX_EN Port 1 - Non-stretched TX_EN signal from the Switch Fabric to the PHY.
Note: Link indication does not affect this function.
RX_DV Port 1 - Non-stretched RX_DV signal from the PHY to the Switch Fabric.
