If the flash memory isprogrammed successfully, then the controller configures the FPGAs. Ifflash memory is not programmed successfully, then the controller waitsfor commands from the PC or microprocessor. The receiver decodes thecommands it receives from the PC or microprocessor as one of thefollowing:■■Program flash memoryConfigure FPGA10–2 Altera CorporationConfiguration Handbook, Volume 2 April 2007
