FPGA_PROG_B Pushbutton SW9 (Active-Low)
[Figure
Switch SW9 grounds the FPGA's PROG_B pin when pressed. This action initiates an FPGA
reconfiguration. The FPGA_PROG_B signal is connected to FPGA U1 pin AJ11.
See UG470, 7 Series FPGAs Configuration User Guide for further details on configuring the
7 series FPGAs.

Configuration Mode and Upper Linear Flash Address Switch (SW11)
[Figure
FPGA Configuration Mode: DIP switch SW11 positions 3, 4, and 5 control which
configuration mode is used at power-up or when the PROG pushbutton is pressed.
Linear BPI Flash Upper Addresses: DIP switch SW11 positions 1 and 2 control the setting
of address bits FLASH_A25 and FLASH_A24. The mode signals FPGA_M2, _M1 and _M0
are connected to FPGA U1 pins AJ10, AK10 and AL10 respectively. Configuration mode is
used at power-up or when the PROG pushbutton is pressed.
