Dual-Ethernet



Question about Ethernet configuration:
The ETRAX 100LX uses a standard MII Interface for the PHY part of the
Ethernet. I should be able to interchange the PHY part with any chips,
that are supporting the MII Interface, for example the Intel LXT972. Is
this correct?
 
 
Dual Ethernet wit LXT972?
In the Intel documentation it's said, the MDIO Management protocol
allows one controller to communicate between two LXT972A chips. Pin
ADDR0 is set high or low to determine the chip address. Does the ETRAX
100LX support this feature through the MDIO?
