Desc ription
GMII and MII Receive Data. Symbols
received on the cable are decoded and pre-
sented on RXD[7:0] in 1000BASE-T mode.
In MII mode, RXD[3:0] are used in
100BASE-TX and 10BASE-T modes. In MII
mode, RXD[7:4] are driven low.
RXD[7:0] is synchronous to RX_CLK.
GMII and MII Carrier Sense. CRS asserts
when the receive medium is non-idle. In half-
duplex mode, CRS is also asserted during
transmission. CRS assertion during half-
duplex transmit can be disabled by program-
ming register 16.11 to 0.
GTX_CLK, and TX_CLK.
GMII and MII Collision. In 10/100/
1000BASE-T full-duplex modes, COL is
always low. In 10/100/1000BASE-T half-
duplex modes, COL asserts only when both
the transmit and receive media are non-idle.
In 10BASE-T half-duplex mode, COL is
asserted to indicate signal quality error
(SQE). SQE can be disabled by clearing reg-
ister 16.2 to zero.
COL is asynchronous to RX_CLK,
GTX_CLK, and TX_CLK.
CRS is asynchronous to RX_CLK,
