Port 0 Transmit clock output
Port 0 Carrier Sense. Please connect this signal to MII0_TX_EN
enable signal.
Pull-Down with a 4.7KOhm resistor to ground. (Reverse MII mode
only support full duplex mode)
Port 0 Transmit data valid. MII0_TX_EN is asserted high when valid
data is present on transmit data bus [3:0].
Port 0 Transmit data bit 0 synchronously with respect to the rising
edge of MII0_TX_CLK.
Port 0 Transmit data bit 1 synchronously with respect to the rising
edge of MII0_TX_CLK.
Port 0 Transmit data bit 2 synchronously with respect to the rising
edge of MII0_TX_CLK.
Port 0 Transmit data bit 3 synchronously with respect to the rising
edge of MII0_TX_CLK.
Port 0 Transmit clock output
Port 0 Receive data enable. MII0_RX_DV is asserted high to indicate
a valid receive data bus [3:0]
Port 0 Receive data bit 0 synchronously with respect to the rising edge
of MII0_RX_CLK.
Port 0 Receive data bit 1 synchronously with respect to the rising edge
of MII0_RX_CLK.
Port 0 Receive data bit 2 synchronously with respect to the rising edge
of MII0_RX_CLK.
Port 0 Receive data bit 3 synchronously with respect to the rising edge
of MII0_RX_CLK.
Note: Pull-Down with a 4.7K ohm resistor to ground
MII management Data. Serial data input/output transferred from/to the
external connected MAC device. The transfer protocol should
conform to the IEEE 802.3u MII spec.
MII management clock input from the externally connected Ethernet
MAC device. All data transferred on MII0_MDIO are synchronized to
the rising edge of this clock.
Note: P0SMR0 Slave MDIO Register need to be programmed.
