EEPROM Chip Selection
Port 1 Link / Active LED
It is the combined LED of link and carrier sense signal
of the internal PHY1
Port 1 Speed LED
Its low output indicates that the internal PHY1 is
operated in 100M/S, or it is floating for the 10M mode of
the internal PHY1
Port 0 Link / Active LED
It is the combined LED of link and carrier sense signal
of the internal PHY0
Port 0 Speed LED
Its low output indicates that the internal PHY0 is
operated in 100M/S, or it is floating for the 10M mode of
the internal PHY0
