    Operation – Quick Setup 2.2.1 Power Supply The DP83826EVM power is supplied by the 5-12V input connection in Figure 3. Single supply operation uses on-board LDOs to generate the voltages required for operating various sections of the EVM. Power can also be supplied externally to individual voltage rails.

    The webpage also contains the User’s Guide for installing and using the software. Because the MSP430 is on-board the DP83826EVM, it is not necessary to purchase a separate MSP430 Launchpad kit and connect to the PHY using wires. In the case the on-board MSP430 cannot be used for some reason, MDIO and MDC pins are also broken out on J1 and J2 pins, respectively.

    Configurations Options 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.
