Transmit Coding Error.
When driven high, this signal causes the encoder to inten-
tionally corrupt the byte being transmitted across the MII (00100 will be transmitted).
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 (register 30, bit 1) is active-high, this pin
is ignored.
Receive Enable.
When this pin is high, the outputs (RXD[3:0], RX_ER, RX_CLK,
RX_DV) are enabled. This pin has an internal 100
k
pull-up resistor.

Description
Management Data Clock.
This is the timing reference for the transfer of data on
the MDIO signal. This signal may be asynchronous to RX_CLK and TX_CLK. The
standard clock rate is 2.5 MHz, the maximum clock rate is 12.5 MHz. When running
MDC above 6.25 MHz, MDC must be synchronous with LSCLK and have a setup time
of 15 ns and a hold time of 5 ns with respect to LSCLK.
Management Data Input/Output.
This I/O is used to transfer control and status infor-
mation between LU6612 and the station management. Control information is driven by
the station management synchronous with MDC. Status information is driven by the
LU6612 synchronous with MDC.
