2. SOFTWARE MODE CONTROL

The CDB42L52 may be used with the Microsoft Windows®-based FlexGUI graphical user interface, allowing soft-

ware control of the CS42L52, FPGA and CS8421 registers. The latest control software may be downloaded from

www.cirrus.com/msasoftware. Step-by-step instructions for setting up the FlexGUI are provided as follows:

1. Download and install the FlexGUI software as instructed on the Website.

2. Connect and apply power to the +5.0 VP binding post.

3. Connect the CDB to the host PC using a USB cable.

4. Launch the Cirrus FlexGUI. Once the GUI is launched successfully, all registers are set to their default reset

state.

5. Refresh the GUI by clicking on the “Update” button. The default state of all registers are now visible.

For standard set-up:

6. Set up the signal routing in the “Board Configuration” tab as desired.

7. Set up the CS42L52 in the “CODEC Configuration”, “Analog Input Volume”, “DSP Engine” and “Analog and

PWM Output Volume” tab as desired.

8. Begin evaluating the CS42L52.

For quick set-up, the CDB42L52 may, alternatively, be configured by loading a predefined sample script file:

9. On the File menu, click "Restore Board Registers..."

10. Browse to Boards\CDB42L52\Scripts\.

11. Choose any one of the provided scripts to begin evaluation.

To create personal scripts files:

12. On the File menu, click "Save Board Registers..."

13. Enter any name that sufficiently describes the created setup.

14. Choose the desired location and save the script.

15. To load this script, follow the instructions from step 9 above.
