When it is pulled high, the LED mode is mode 1; Otherwise it is mode 0
Crystal 25MHz Out
Crystal 25MHz In
20Mhz Clock Output
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.
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
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
