2. SOFTWARE MODE
The CDB42438 is shipped with a Microsoft Windows
®
based GUI, which allows control over the
CS42438 and FPGA registers. Interface to the GUI is provided using an RS-232 serial cable.
Once the appropriate cable is connected between the CDB42438 and the host PC, load “Flex-
Loader.exe” from the CDB42438 directory. Once loaded, all registers are set to their default re-
set state. The GUI’s “File” menu provides the ability to save and load script files containing all of
the register settings. Sample script files are provided for basic functionality. Refer to section 3.1
on page 9 for details.
2.1 Advanced Register Debug Tab
The Advanced Register Debug tab provides low level control over the CS42438 and FPGA
individual register settings. Each device is displayed on a separate tab. Register values can
be modified bit-wise or byte-wise. For bit-wise, click the appropriate push button for the de-
sired bit. For byte-wise, the desired hex value can be typed directly in the register address
box in the register map.
