Setting the FPGA Mode Select Pins
To configure the FPGA from NOR Flash, set the FPGA configuration mode pins for BPI Up
mode, as shown in Table 11-3 . The Spartan-3A FPGA family does not support the BPI
Down mode that is available in the Spartan-3E FPGA family.
Also be sure to disable the Platform Flash PROM by removing jumper J46, as shown in
Table 11-3 .
