restart the auto-negotiation process through MDIO using PHY address increasingly from 01000b to
01111b. After restarting auto-negotiation, the T71L6808A will continuously poll the link status and
link partner's ability which including speed, duplex and flow control of the PHY devices via MDIO.

24LC02 Interface
The 24LC02 interface is a 2-wire serial EEPROM interface providing 2K bits storage space. After
power on reset, the T71L6808A uses Random Read and Sequential Read commands to auto-load
configuration settings, pause frame source address and so on. After auto-loaded, the 24LC02
interface pins SCL and SDA are tri-stated for on-line updating 24LC02 contents through a parallel
port.
