TXD[3:0] are synchronous to TXCLK, which is generated by MAC. TXCLK is running at 25M in 100M mode and
2.5M in 10M mode. When TXEN is asserted, it indicates that TXD[3:0] contains valid data to be transmitted. When
TXEN is de-asserted, value on TXD[1:0] should be ignored.

When ADM7001 operates in half duplex mode, either 10M or 100M, it will assert COL signal whenever it detects
there is collision on the medium.
