Description
Transmit Error.
When both TXER and TXEN are asserted, the transmit error symbol is
transmitted onto the cable.
When TXER is asserted and TXEN is de-asserted, the carrier extension
symbol is transmitted onto the cable.
Connect to GND if MAC does not have a TXER pin.
The continuous receive reference clock will be 125MHz, 25MHz, or
2.5MHz. It is derived from the received data stream.
Receive Data.
Data is transmitted from PHY to MAC via RXD[7:0].
Receive Data Valid.
Receive Error.
When both RXER and RXDV are asserted, an error symbol is received
from the cable.
When RXER is asserted and RXDV is de-asserted, it means false carrier
or carrier extension symbol is detected on the cable.
Collision In Half Duplex Mode.
Carrier Sense.
