Receive Data (RXD[3:0]) is clocked from the external PHY synchronously with RX_CLK. The RX_CLK signal is
2.5 MHz for 10 Mbps operation and 25 MHz for 100 Mbps operation. RX_DV is asserted by the PHY from the first
nibble of the preamble in 100 Mbps operation or first nibble of SFD for 10 Mbps operation. The data on RXD[3:0]
is not accepted by the MAC if RX_DV is low or RX_ERR is high (in DTE mode). RX_ERR should be tied low when
in DCE Mode.

In RMII Mode, TX_EN is high with the first bit of the preamble. The TXD[1:0] is synchronous with the 50 MHz
REF_CLK. For 10 Mbps operation, the data bit outputs are updated every 10 clocks
.
