Port 0 50MHz RMII reference clock input ± 50 PPM with a duty cycle
between 35% and 65% inclusive.
Port 0 Transmit data valid synchronously with respect to the rising edge
of MII0_REFCLK. MII0_TX_EN is asserted high when valid data is
present on transmit data bus [1:0].
Port 0 Transmit data bit 0 synchronously with respect to the rising edge
of MII0_REFCLK.
Port 0 Transmit data bit 1 synchronously with respect to the rising edge
of MII0_REFCLK.
Port 0 50 MHz Reference clock output if ICR [12] is set to one.
Port 0 Receive data enable synchronously with respect to the rising
edge of MII0_REFCLK. MII0_CRSDV is asserted high to indicate a
valid receive data bus [1:0]
Port 0 Receive data bit 0 synchronously with respect to the rising edge
of MII0_REFCLK.
Port 0 Receive data bit 1 synchronously with respect to the rising edge
of MII0_REFCLK.
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.
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.
