The host bus interface provides a FIFO interface for the transmit and receive data paths, as well as
an interface for the LAN9218 Control and Status Registers (CSR’s).
The host bus interface is the primary bus for connection to the embedded host system. This interface
models an asynchronous SRAM. TX FIFO, RX FIFO, and CSR’s are accessed through this interface.
Programmed I/O transactions are supported.
The LAN9218 host bus interface supports 32-bit and 16-bit bus transfers. Internally, all data paths are
32-bits wide. The LAN9218 can be interfaced to either Big-Endian or Little-Endian processors.
