35 / 70 page MII Interface Slave Controller – ET1200 Hardware Description III-25 Table 31: MII Interface signals Signal Direction Description LINK_MII IN Input signal provided by the PHY if a 100 Mbit/s (Full Duplex) link is established RX_CLK IN Receive Clock RX_DV IN Receive data valid RX_D[3:0] IN Receive data (alias RXD) RX_ERR IN Receive error (alias RX_ER) TX_ENA OUT Transmit enable (alias TX_EN) TX_D[3:0] OUT Transmit data (alias TXD) MI_CLK OUT Management Interface clock (alias MCLK) MI_DATA BIDIR Management Interface data (alias MDIO) PHYAD_OFF IN Configuration: PHY address offset MI_DATA must have an external pull-up resistor (4.7 k Ω recommended for ESCs). MI_CLK is driven rail-to-rail, idle value is High. 4.2 PHY Address Configuration The ET1200 addresses Ethernet PHYs using logical port number (or PHY address register value) plus PHY address offset. Typically, the Ethernet PHY addresses should correspond with the logical port number, so PHY addresses 0-3 are used. A PHY address offset of 16 can be applied which moves the PHY addresses to 16-19 by inverting the MSB of the PHY address internally. If both alternatives cannot be used, the PHYs should be configured to use an actual PHY address offset of 1, i.e., PHY addresses 1-4. The PHY address offset configuration of the ET1200 remains 0. Refer to Section I for more details about PHY addressing. |
