CONFIG0
Ipd/O
MII Mode: MII Collision Detect output
Config. Mode: The pull-up/pull-down value is latched as CONFIG0 at the de-assertion
of reset. See the Strapping Options section for details.

CONFIG1
Ipd/O
MII Mode: MII Carrier Sense Output
Config. Mode: The pull-up/pull-down value is latched as CONFIG1 at the de-assertion

LED0/
NWAYEN
Ipu/O
LED Output: Programmable LED0 Output
Config. Mode: Latched as auto-negotiation enable (Register 0h, Bit [12]) at the de-
assertion of reset. See the Strapping Options section for details.
The LED0 pin is programmable using Register 1Fh Bits [5:4], and is defined as
follows:
LED Mode = [00]
Link/Activity Pin State LED Definition
No link High OFF
Link Low ON
Activity Toggle Blinking
LED Mode = [01]
Link Pin State LED Definition
No link High OFF
Link Low ON
LED Mode = [10], [11] Reserved
Note:
4. MII TX Mode: The TXD[3:0] bits are synchronous with TXC. When TXEN is asserted, TXD[3:0] presents valid data from the MAC.
