A.1 Reference .csv Files

The .csv files are bundled with the DEM-DAI3793A/3794A EVM Controller. These files enable users to execute register settings corresponding to the specific operating modes discussed in the product data sheet by importing them into the software.

Note that each .csv file (listed in Table A-1) must be implemented after an All Active operation is performed with the power_on.csv command; otherwise, these files will not work properly.

An All Active operation is recommended to start up the device, and can be executed by just clicking the All Power On button, as discussed in Section 3.2.
