Figure 6 • MII Registers GUI Window
Be sure the device is up and running by reading MII Register 0. It should read back 0 × 1040. Reading
back all 0’s or all 1’s indicates a problem. A checked box means the bit is set to “1,” if unchecked it is
“0.”

Board Initialization and Running PGY Scripts
Once the evaluation board connectivity has been established and confirmed, the PHY should be
initialized. Initialization can be accomplished by running an init-script sequence, such as performed by
the pre- and post-reset functions of the PHY API standalone app.
While the init-script sequence may not required for specific operational modes, an init-script sequence
is highly recommended to ensure correct performance over the greatest set of user scenarios for the
PHY. After initialization is performed, refer to the PHY Datasheet section on Configuring of the PHY and
PHY Interfaces for the desired application.
In order to execute an init-script, double-click on “Run PHY Script” within the GUI Connection Window
to launch the Run PHY Script window as shown in Figure 7. This enables a user to load a script to
configure the device rather than navigating through Registers pages. Click “Load” button, browse to a
desired script file via the pop-up panel, finally click “Run” button. After execution is completed, you
should see read-back values in decimal as shown in the following figure.
The script syntax is command, phy address (in decimal), register address (in decimal), and register
content (in either hexadecimal or decimal).
