12.3.2 LED Function Definitions when LED_FUN[1:0] = 11b
When LED Function 1-0 (LED_FUN[1:0]) is 11b, the following LED rules apply:
„ The LED pins are push-pull drivers.
„ The LED polarity does not depend upon the led_pol_strap[5:0] LED polarity hard-straps. The LED
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.
When LED Function 1-0 (LED_FUN[1:0]) is 11b, the following LED function definitions apply:
„ 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.
Note: Link indication does not affect this function.
„ TX_EN Port 2 - Non-stretched TX_EN signal from the Switch Fabric to the PHY.
Note: Link indication does not affect this function.
„ RX_DV Port 2 - Non-stretched RX_DV signal from the PHY to the Switch Fabric.
Note: Link indication does not affect this function.
