Pull-Down with a 4.7KOhm resistor to ground. Reverse MII mode
only support full duplex.
Port 1 Transmit data valid. MII1_TX_EN is asserted high when valid
data is present on transmit data bus [3:0].

Port 1 Receive clock output
Port 1 Receive data enable. MII1_RX_DV is asserted high to indicate
a valid receive data bus [3:0]
Port 1 Receive data bit 0 synchronously with respect to the rising
edge of MII1_RX_CLK.
Port 1 Receive data bit 1 synchronously with respect to the rising
edge of MII1_RX_CLK.
Port 1 Receive data bit 2 synchronously with respect to the rising
edge of MII1_RX_CLK.
Port 1 Receive data bit 3 synchronously with respect to the rising
edge of MII1_RX_CLK.
MII management data. Serial data input/output transferred from/to
the externally connected MAC device. The transfer protocol should
conform to the IEEE 802.3u MII spec.
MAC device. All data transferred on MDIO are synchronized to the
rising edge of this clock.
Note: P1SMR0 Slave MDIO Register need to be programmed
