Receive data bus from PHY, data sampled synchronously with respect
to ETH_RXCLK0
Receive data valid, used to inform the MII interface that the Ethernet
PHY is sending data. Should be pulled low through a 10-KΩ resistor
when not being utilized in the system.
Asserted by the PHY when a collision is detected by the PHY. Should be
pulled low through a 10-KΩ resistor when not being utilized in the
system.
Asserted by the PHY when the transmit medium or receive medium is
active. De-asserted when both the transmit and receive medium are
idle. Remains asserted throughout the duration of a collision condition.
PHY asserts CRS asynchronously and de-asserts synchronously, with
respect to ETH_RXCLK0. Should be pulled low through a 10-KΩ resistor
when not being utilized in the system.
Management data output. Provides the write data to both PHY devices
connected to each MII interface.
Should be pulled low through a 10-KΩ resistor when not being utilized in
the system.
Management data clock. Management data interface clock is used to
clock the MDIO signal as an output and sample the MDIO as an input.
The ETH_MDC is an input on power up and can be configured to be an
output through an Intel API as documented in the Intel
Software Programmer’s Guide.
Externally supplied transmit clock.
Should be pulled low through a 10-KΩ resistor when not being utilized in
the system.
Transmit data bus to PHY, asserted synchronously with respect to
ETH_TXCLK1.
Indicates that the PHY is being presented with nibbles on the MII
interface. Asserted synchronously, with respect to ETH_TXCLK1, at the
first nibble of the preamble, and remains asserted until all the nibbles of
a frame are presented.
Externally supplied receive clock.
Should be pulled low through a 10-KΩ resistor when not being utilized in the
system.
Receive data bus from PHY, data sampled synchronously, with respect
to ETH_RXCLK1.
Receive data valid, used to inform the MII interface that the Ethernet

Asserted by the PHY when the transmit medium or receive medium are
active. De-asserted when both the transmit and receive medium are
idle. Remains asserted throughout the duration of collision condition.
