This pin is also used as a strap pin to define the LED modes.
When it is pulled high, the LED mode is mode 1; Otherwise it is mode 0
Note: The pins EECS,EECK and EEDO are all have a pulled down resistor about 60k ohm internally

Its low output indicates that the internal PHY is operated in 100M/S, or it
is floating for the 10M mode of the internal PHY
Full-duplex LED
In LED mode 1, Its low output indicates that the internal PHY is operated
in full-duplex mode, or it is floating for the half-duplex mode of the internal
PHY
In LED mode 0, Its low output indicates that the internal PHY is operated
in 10M mode, or it is floating for the 100M mode of the internal PHY
Link LED
In LED mode 1, it is the combined LED of link and carrier sense signal of
the internal PHY
In LED mode 0, it is the LED of the carrier sense signal of the internal
PHY only
