2.6. DM9000 Network controller
The DM9000 network controller provides 100Mbit Ethernet
connectivity to the system. It is decoded into the CS0 address
space by the system CPLD as it uses the WAIT line to extend
I/O cycles as necessary.
The DM9000 may interrupt the ML675001. The IRQ is connected
to the ML675001 IRQ0 signal. The interrupt is shared with the
Clock and is also presented on pin A13 of the PL4 connector.
