6.3.1. F-tile Triple-Speed Ethernet System with MII/GMII

Figure 42.  Triple-Speed Ethernet System with MII/GMII with Register Initialization Recommendation

Use the following recommended initialization sequences for the example shown in the figure above.

  1. External PHY Initialization using MDIO

    //Assume the External PHY Address is 0x0A

    mdio_addr0 = 0x0A

    //External PHY Register will Map to MDIO Space 0

    Read/write to MDIO space 0 (dword offset 0x80 - 0x9F) = Read/write to PHY Register 0 to 31

  2. MAC Configuration Register Initialization
    1. Disable MAC Transmit and Receive Datapath Disable the MAC transmit and receive datapath before performing any changes to configuration.

      //Set TX_ENA and RX_ENA bit to 0 in Command Config Register

      Command_config Register = 0x00802220

      //Read the TX_ENA and RX_ENA bit is set 0 to ensure TX and RX path is disable

      Wait Command_config Register = 0x00802220

    2. MAC FIFO Configuration

      Tx_section_empty = Max FIFO size - 16

      Tx_almost_full = 3

      Tx_almost_empty = 8

      Rx_section_empty = Max FIFO size - 16

      Rx_almost_full = 8

      Rx_almost_empty = 8

      //Cut Through Mode, Set this Threshold to 0 to enable Store and Forward Mode

      Tx_section_full = 16

      //Cut Through Mode, Set this Threshold to 0 to enable Store and Forward Mode

      Rx_section_full = 16

    3. MAC Address Configuration

      //MAC address is 00-1C-23-17-4A-CB

      mac_0 = 0x17231C00

      mac_1 = 0x0000CB4A

    4. MAC Function Configuration

      //Maximum Frame Length is 1518 bytes

      Frm_length = 1518

      //Minimum Inter Packet Gap is 12 bytes

      Tx_ipg_length = 12

      //Maximum Pause Quanta Value for Flow Control

      Pause_quant = 0xFFFF

      //Set the MAC with the following option:

      // 100Mbps, User can get this information from the PHY status/PCS status

      //Full Duplex, User can get this information from the PHY status/PCS status

      //Padding Removal on Receive

      //CRC Removal

      //TX MAC Address Insertion on Transmit Packet

      //Select mac_0 and mac_1 as the source MAC Address

      Command_config Register = 0x00800220

    5. Reset MAC
      Intel recommends that you perform a software reset when there is a change in the MAC speed or duplex. The MAC software reset bit self-clears when the software reset is complete.

      //Set SW_RESET bit to 1

      Command_config Register = 0x00802220

      Wait Command_config Register = 0x00800220

    6. Enable MAC Transmit and Receive Datapath

      //Set TX_ENA and RX_ENA to 1 in Command Config Register

      Command_config Register = 0x00800223

      //Read the TX_ENA and RX_ENA bit is set 1 to ensure TX and RX path is enable

      Wait Command_config Register = 0x00800223
