This window contains drop-down menus that select protocol (SPI or I
device address.The menu does not pop up if the GUI starts in Demo mode. In this case, uncheck the Demo
Mode checkbox. If the interface must be updated again, toggle the Demo Mode checkbox for the menu to

The SDO pin on the DACx3004W is connected to the GPIO2 output from the onboard controller. Before
configuring the SDO pin as an output to enable readback, remove J6 to disable the GPIO outputs from the
onboard controller or remove R13 on the DAC63004WCSP-EVM to disconnect the GPIO2 pin from the SDO pin.
