Indicates a transmit error condition.
Note: This input is ignored during 10BASE-T
operation.
Indicates the presence of valid data on TXD[7:0]
Used to latch data from the MAC into the PHY.
MII (100BASE-TX): 25MHz
MII (10BASE-T): 2.5MHz
Note:
For 1000BASE-T operation, GTXCLK is
used as the transmit clock. TXCLK is not
used in 1000BASE-T mode.
125MHz clock used to latch data from the MAC into
the PHY in 1000BASE-T mode.
