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

It is used as the clock signal for the external MII device’s clock is 20MHz
This pin has a pulled down resistor about 60k ohm internally.
When pin TEST5 state is high, this pin act as the system clock.

Speed LED
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

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
