GENERAL DESCRIPTION
DM9000 ISA to Ethernet MAC Controller with Integrated 10/100 PHY The DM9000 supports 8-bit, 16-bit and 32-bit uP interfaces to internal memory accesses for different processors. The PHY of the DM9000 can interface to the UTP3, 4, 5 in 10Base-T and UTP5 in 100Base-TX. It is fully compliant with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the DM9000 to take the maximum advantage of its abilities. The DM9000 also supports IEEE 802.3x full- duplex flow control. This programming of the DM9000 is very simple, so user can port the software drivers to any system easi
