... The user has two options for the data source: USB and File. If the USB setup is selected, the evaluation software will be ready to communicate with the CDB5534U via the USB connection. At this point, the Part menu item is active and the appropriate CS553x device can be selected. If the File source is selected, the evaluation software will prompt the user to select the appropriate data file ...
