3.7. Ethernet interface

The Ethernet interface is implemented using a SMCS LAN9118 10/100 Ethernet controller. The LAN9118 incorporates a Media ACcess (MAC) Layer, a PHYsical (PHY) layer, Host Bus Interface (HBI), receive and transmit FIFOs, power management controls, and a serial configuration EEPROM interface.

The HBI models an asynchronous SRAM and interfaces directly to the Northbridge static memory bus.

When manufactured, an ARM value for the Ethernet MAC address is loaded into a configuration EEPROM connected to the Ethernet controller.

See Ethernet for details of PB-A8 usage and the SMC LAN9118 Data Sheet for full programming details.
