7.21 Gigabit Ethernet (GbE) Switch Subsystem
www.ti.com
The Gigabit Ethernet (GbE) switch subsystem provide an efficient interface between the TMS320TCI6604 DSP and
the networked community. The GbE switch subsystem supports 10Base-T (10 Mbits/second [Mbps]), and
100BaseTX (100 Mbps), in half- or full-duplex mode, and 1000BaseT (1000 Mbps) in full-duplex mode, with
hardware flow control and quality-of-service (QOS) support. The GbE switch subsystem is coupled with network
coprocessor. For more information, see the Gigabit Ethernet (GbE) Switch Subsystem for KeyStone Devices User
Guide in ‘‘Related Documentation from Texas Instruments’’ on page 66.
Each device has a unique MAC address. There are two registers to hold these values, MACID1 (0x02620110) and
MACID2 (0x02620114). All bits of these registers are defined as follows:
