IDLE
Sent after /T/R/ until the MII Transmitter
Enable signal (TXEN) is received
First nibble of SSD, translated to “0101”
following IDLE, else MII Receive Error
(RXER)
Sent for rising MII Transmitter Enable
signal (TXEN)
Second nibble of SSD, translated to
“0101” following J, else MII Receive Error
(RXER)
Sent for rising MII Transmitter Enable
signal (TXEN)
First nibble of ESD, causes de-assertion
of CRS if followed by /R/, else assertion
of MII Receive Error (RXER)
Sent for falling MII Transmitter Enable
signal (TXEN)
Second nibble of ESD, causes de-asser-
tion of CRS if following /T/, else assertion
of MII Receive Error (RXER)
Sent for falling MII Transmitter Enable
signal (TXEN)
Transmit Error Symbol
Sent for rising MII Transmit Error (TXER)
INVALID, MII Receive Error (RXER) if
during MII Receive Data Valid (RXDV)
INVALID
INVALID, MII Receive Error (RXER) if
during MII Receive Data Valid (RXDV)
INVALID
SLEEP, Indicates to receiver that the
transmitter will be going to LPI
Sent due to LPI. Used to tell receiver
before transmitter goes to LPI. Also used
for refresh cycles during LPI.
INVALID, MII Receive Error (RXER) if
