The Ethernet interface is implemented in an external SMCS LAN9118
10/100 Ethernet single-chip MAC and PHY. The internal registers
of the LAN9118 are memory-mapped onto the static memory bus and
occupy locations starting at base address
|Location||Board (LAN9118 chip)|
|Memory base address|
|DMA||None, use memory to memory DMA to access the FIFO buffers in the LAN9118 Host Bus Interface.|
|Release version||Custom interface to external controller.|
|Reference documentation||LAN9118 Data Sheet (see also Ethernet interface).|
Refer to the LAN9118 application note or to the self test program supplied on the CD for additional information.
When manufactured, an ARM value for the Ethernet MAC address and the register base address are loaded into the EEPROM. The register base address is 0. The MAC address is unique, but can be reprogrammed if required.
