The KC705 Evaluation Kit provides the adapter cable shown in
the KC705 board from the ATX power supply 4-pin peripheral connector. The Xilinx part
number for this cable is 2600304, and is equivalent to Sourcegate Technologies part number
AZCBL-WH-1109-RA4. For information on ordering this cable, see
X-Ref Target - Figure 1-32
FPGA_PROG_B Pushbutton SW14 (Active-Low)
[Figure
Switch SW14 grounds the FPGA PROG_B pin when pressed. This action initiates an FPGA
reconfiguration. The FPGA_PROG_B signal is connected to FPGA U1 pin K10.
See 7 Series FPGAs Configuration User Guide (UG470)
