The High-Speed Serial (HSS) transmit frame signal can be configured as
an input or an output to allow an external source to be synchronized with
the transmitted data. Often known as a Frame Sync signal. Configured as
an input upon reset.
Should be pulled low with a 10-KΩ resistor when not being utilized in the
system.
Transmit data out. Open Drain output.
Must be pulled high with a 10-KΩ resistor to V
The High-Speed Serial (HSS) transmit clock signal can be configured as
an input or an output. The clock can be a frequency ranging from 512 KHz
to 8.192 MHz. Used to clock out the transmitted data. Configured as an
input upon reset. Frame sync and Data can be selected to be generated
on the rising or falling edge of the transmit clock.
Should be pulled low with a 10-KΩ resistor when not being utilized in the
system.
The High-Speed Serial (HSS) receive frame signal can be configured as
an input or an output to allow an external source to be synchronized with
the received data. Often known as a Frame Sync signal. Configured as an
input upon reset.
Should be pulled low with a 10-KΩ resistor when not being utilized in the
system.
Receive data input. Can be sampled on the rising or falling edge of the
receive clock.
Should be pulled low through a 10-KΩ resistor when not being utilized in
the system.
The High-Speed Serial (HSS) receive clock signal can be configured as
an input or an output. The clock can be from 512 KHz to 8.192 MHz. Used
to sample the received data. Configured as an input upon reset.
Should be pulled low with a 10-KΩ resistor when not being utilized in the
system.

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_TXCLK0.
Indicates that the PHY is being presented with nibbles on the MII
interface. Asserted synchronously, with respect to ETH_TXCLK0, 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.
