High Performance Single-Chip 10/100 Non-PCI Ethernet Controller
Datasheet
The LAN9118 host bus interface supports 32-bit and 16-bit bus transfers; internally, all data paths are
32-bits wide. The LAN9118 can be interfaced to either Big-Endian or Little-Endian processors in either
32-bit or 16-bit external bus width modes of operation.
The host bus data Interface is responsible for host address decoding and data bus steering. The host
bus interface handles the 16 to 32-bit conversion when the LAN9118 is configured with a 16-bit host
interface. Additionally, when Big Endian mode is selected, the data path to the internal controller
registers will be reorganized accordingly.
