Table 3.  Parameter Settings
Parameter Legal Values Descriptions
Device Density 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048 Density of the flash device used in Mb.
Disable dedicated Active Serial interface — Routes the signals to the top level of your design. Enable this when you want to include the Serial Flash Loader Intel FPGA IP in your design.
Enable SPI pins interface — Translates the signals to the SPI pin interface.
Number of Chip Select used
