4.1 MDIO Register Access

To update or read the registers of the device, the user can simply connect the DP83826EVM to a computer and use the USB-2-MDIO software. The EVM is designed to easily enable and test strap functionality through software instead without the need to modify the board and hardware. This allows for simple hardware and software support for those that do not have MDIO communication capability. The register map used for the DP83826EVM can be found in section 8.7 of the DP83826E Datasheet.

More information on how to access the DP83826 MDIO status and control registers can be found in the USB-2-MDIO Software User's Guide .
