2.3.1 Setup Menu
Setup allows user to establish a USB communication connection with CDB5464U board or select a pre-
viously saved data file for further analysis.
If the USB item in the Setup menu is selected, the evaluation software will poll the CDB5464U, verifying

information are read from the board and displayed on the screen. See Figure 3. Due to improvements to
the software or new features being added, the version displayed may be different than the image shown
here.
