Description
TX_CLK[D:A]
Transmit Clock.
25 MHz clock output in 100 Mbits/s mode, 2.5 MHz output
in 10 Mbits/s MII mode, 10 MHz output in 10 Mbits/s serial mode. TX_CLK
provides timing reference for the transfer of the TX_EN, TXD, and TX_ER
signals sampled on the rising edge of TX_CLK.
Transmit Data.
4-bit parallel input synchronous with TX_CLK. When
SERIAL_SEL is active-high and 10 Mbits/s mode is selected, only
TXD[0][D:A] are valid.
TXD[3:0][D:A]
I
TX_EN[D:A]
I
Transmit Enable.
When driven high, this signal indicates there is valid data
on TXD[3:0]. TX_EN is synchronous with TX_CLK. When SERIAL_SEL is
active-high and 10 Mbits/s mode is selected, this pin indicates there is valid
data on TXD[0].
Transmit Coding Error.
When driven high, this signal causes the encoder
to intentionally corrupt the byte being transmitted across the MII (00100 will
be transmitted).
Transmit Data[4].
When the encoder/decoder bypass bit is set, this input
serves as the TXD[4] input. When in 10 Mbits/s mode and SERIAL_SEL is
active-high, this pin is ignored.
MII Enable.
For normal MII mode of operation (nonbused mode), MII_EN
for each channel must be tied high to enable each individual port being
used.
