Serial Modes
Each Ethernet port can operate in one of three serial modes: 10BaseT, 10BaseFL, or AUI, The serial mode is set
after RESET by the state of DData[23:0]. These values can be overwritten in the Port Control register.
9.14
Physical Interface Circuitry
Since the digital portion of the Ethernet PHY is integrated in the GT-482xx, only a small amount of external logic is
needed to implement the standard physical interfaces. The GT-482xx interfaces directly with the AMD’s QuIET
chip (by setting the GT-482xx to work in pseudo-AUI mode) or with the Tamarack TC3001 (setting the GT-482xx
to work in 10Base-T mode).
Information about the Tamarack TC3001 can be found at the following URL: www.tmi.com.tw. Information about
the AMD QuIET chip can be found at the following URL: www.amd.com. Schematics for both implementations are
available upon request.
NOTE: Galileo Technology may support other physical interfaces in the future. Please contact your local Galileo
Technology FAE for further updates.

Serial Link Status Indication
This link is used to serially shift the Link Status of ports 1 to 11 from the external PHY. LEDClk and LEDStb are
used to clock and strobe the data (assertion of LEDStb indicates the beginning of the link data stream). The serial
link status indication of port 0 is provided separately at LinkStatus[0] pin.
Figure 9 illustrates a port 1 link fail.
