Functional Description
f
significant DATA bits to the FPGAs or FPGA chains. Leave the most
significant DATA bit (DATA[3]) unconnected. Similarly, for 5-, 6- or 7-bit
concurrent chains you can select the 8-bit PS mode.
Figure 2–3 shows the schematic for configuring multiple FPGAs
concurrently in the PS mode using an enhanced configuration device.
For specific details on configuration interface connections including
pull-up resistor values, supply voltages, and MSEL pin settings, refer to
the appropriate FPGA family chapter in the Configuration Handbook.
