 Networked device using
network processor with MII
such as networking gaming
and modems
 Bridging devices between
other networking
technologies and MII
 PCI Card, the dLAN 200
AVmodule 6400 connects to
a PCI/MII bridge chip
MAC Mode  Ethernet to HomePlug
Adapters
 Device with an integrated
PHY available, but no MII
available - use an
inexpensive MII PHY to
make a PHY-to-PHY
connection

operations
2.2 MII Ethernet PHY Configuration
There are additional configuration straps that
are unique to the MII Ethernet PHY mode of
operation shown in Tables 3 to Table 7. Speed
select sets the MII data rate. Auto-negotiation
select enables auto-negotiation or defaults the
MII to speed and duplex settings. After the
modules firmware has been booted the Auto-
