MII Mode of Operation:
Receive data valid, used to inform the MII interface that the Ethernet PHY is sending data. This
MAC interface does not contain hardware hashing capabilities local to the interface.
SMII Mode of Operation:
In Source Synchronous mode of operation, this signal is an input from a synchronous pulse
created once every 10 SMII_RXCLK reference clocks to signal the start of the next 10 bits of data
to be received. SMII_RXCLK Reference clock operates at 125MHz.
When this interface/signal is enabled and is not being used in a system design, the interface/
signal should be pulled high with a 10-KΩ resistor. When this interface is disabled via the NPE-B
Ethernet 0 and/or the NPE Ethernet 1-3 soft fuse (refer to Expansion Bus Controller chapter of
the Intel
and is not being used in a system design, this interface/signal is not required for any connection.
MII Mode of Operation:
Asserted by the PHY when a collision is detected by the PHY. This MAC interface does not
contain hardware hashing capabilities local to the interface.
SMII Mode of Operation:
Not used.
When this interface is disabled via the NPE-B Ethernet 0 and/or the NPE Ethernet 1-3 soft fuse
(refer to Expansion Bus Controller chapter of the Intel
of Network Processors Developer’s Manual) and is not being used in a system design, this
interface/signal is not required for any connection.
