1.2.5.8.3 Ethernet PHY Driver Configurations

PHY Driver Specific User Configurations

• PHY Address:

  • The address of this PHY on the MIIM bus

  • Default value: 0

  • Symbol TCPIP_INTMAC_PHY_ADDRESS

• Use a Function to be called at PHY Reset:

  • Use a callback function when the PHY is reset

  • Default value: false

  • Symbol DRV_ETHPHY_USE_RESET_CALLBACK

• App Function:

  • The reset callback function name

  • Default value: "AppPhyResetFunction"

  • Symbol DRV_ETHPHY_RESET_CALLBACK

• RMII Data Interface:

  • Use RMII data interface for the MAC <-> PHY connection

  • Otherwise it will be MII

  • Default value: depends on platform

  • Symbol TCPIP_INTMAC_PHY_CONFIG_RMII

• Configuration Fuses Is ALT:

  • For platforms that support multiple I/O configuration fuses for the Ethernet pins this will select an alternate I/O pin setting.

  • Otherwise is the default I/O setting

  • Default value: false

  • Symbol TCPIP_INTMAC_PHY_CONFIG_ALTERNATE

• Use The Fuses Configuration:

  • For platforms that support multiple Ethernet I/O pins and MII/RMII configuration fuses this setting will instruct the PHY driver to use the duse settings for configuring the PHY

  • Default value: true

  • Symbol TCPIP_INTMAC_PHY_CONFIG_AUTO

• Delay for the Link Initialization - ms:

  • The value of the delay for the link initialization

  • This insures that the PHY is ready to transmit after it is reset

  • A usual value is > 500 ms up to 2000 ms.

  • The longer the delay, the less chance that the PHY drops packets when the link is established

  • Adjust to your needs.

  • Value is in milliseconds

  • Default value: 500

  • Symbol TCPIP_INTMAC_PHY_LINK_INIT_DELAY, TCPIP_EMAC_PHY_LINK_INIT_DELAY

• PHY Negotiation Time-out - ms:

  • Value of the PHY negotiation initiation time out as per IEEE 802.3 spec.

  • Value is in milliseconds

  • Default value: 1

  • Symbol DRV_ETHPHY_NEG_INIT_TMO

• PHY Negotiation Done Time-out - ms:

  • Value of the PHY negotiation complete time out as per IEEE 802.3 spec.

  • This definition sets the time out of the PHY negotiation complete

  • Value is in milliseconds

  • Notes:

    • See IEEE 802.3 Clause 28 Table 28-9 autoneg_wait_timer value (max 1s).

  • Default value: 2000

  • Symbol DRV_ETHPHY_NEG_DONE_TMO

• PHY Reset Clear Time-out - ms:

  • Value of the PHY Reset self clear time out as per IEEE 802.3 spec.

  • This definition sets the time out of the PHY Reset self clear.

  • Note:

    • See IEEE 802.3 Clause 22 Table 22-7 and paragraph "22.2.4.1.1 Reset" (max 0.5s)

  • Value is in milliseconds

  • Default value: 500

  • Symbol DRV_ETHPHY_RESET_CLR_TMO

• PHY Instances Number:

  • Selects the maximum number of hardware instances that can be supported by the dynamic driver.

  • Note:

    • This value is currently read-only

  • Default value: 1

  • Symbol DRV_ETHPHY_INSTANCES_NUMBER

• PHY Clients Number:

  • Ethernet PHY Maximum Number of Clients

  • This definition selects the maximum number of clients that the Ethernet PHY driver can support at run time.

  • Notes:

    • The MAC driver is the only client of the PHY driver and the number of clients should always be 1.

    • This value is currently read-only

  • Default value: 1

  • Symbol DRV_ETHPHY_CLIENTS_NUMBER

• PHY Peripheral Index Number:

  • This definition selects the Ethernet PHY static index for the driver object reference.

  • Notes:

    • The only value currently supported is 1

    • This value is currently read-only

  • Default value: 1

  • Symbol DRV_ETHPHY_INDEX

• PHY Peripheral ID:

  • Defines the value of the peripheral ID.

  • Notes:

    • The only value currently supported is 1

    • This value is currently read-only

  • Default value: 1

  • Symbol DRV_ETHPHY_PERIPHERAL_ID
