UCS1001 page. When the EVB-USB2642 does not detect an EEPROM or a valid SPI flash image upon power-up, the EVB-USB2642 uses internal default register settings. It sets the Vendor ID, Product ID, Language ID, Device ID and a few other selections from internal ROM code.
The installed SPI flash is initially blank. In this scenario, the internal firmware will execute. External firmware updates can be downloaded via USB using the utility USBDM to the SPI flash. After downloading, the EVB-USB2642 will execute from the SPI flash.
