4.7.5.2
The MII transmit signal timing affects the FEC_TXD[3:0], FEC_TX_EN, FEC_TX_ER, and
FEC_TX_CLK signals. The transmitter functions correctly up to a FEC_TX_CLK maximum frequency
of 25 MHz + 1%. There is no minimum frequency requirement. In addition, the processor clock frequency
must exceed twice the FEC_TX_CLK frequency.

FEC_TX_EN, FEC_TX_CLK, and FEC_TXD0 have the same timing in 10 Mbps 7-wire interface mode.
Test conditions: 25pF on each output signal.
