VC709 Evaluation Board www.xilinx.com 49UG887 (v1.2.1) March 11, 2014Feature DescriptionsSwitches[Figure 1-2, callout 19, 20, and 21]The VC709 board includes a power and a configuration switch:• FPGA_PROG_B , active-Low pushbutton switch SW9 (callout 19)• Configuration mode DIP switch SW11 (callout 20)• Power on/off slide switch SW12 (callout 21)FPGA_PROG_B Pushbutton SW9 (Active-Low)[Figure 1-2, callout 19]Switch SW9 grounds the FPGA PROG_B pin when pressed. This action initiates an FPGAreconfiguration. The FPGA_PROG_B signal is connected to FPGA U1 pin AJ11.See 7 Series FPGAs Configuration User Guide (UG470) [Ref 2]for further details onconfiguring the 7 series FPGAs.Figure 1-21 shows SW9.AV30 GPIO_DIP_SW0 SW2.16AY33 GPIO_DIP_SW1 SW2.15BA31 GPIO_DIP_SW2 SW2.14BA32 GPIO_DIP_SW3 SW2.13AW30 GPIO_DIP_SW4 SW2.12AY30 GPIO_DIP_SW5 SW2.11BA30 GPIO_DIP_SW6 SW2.10BB31 GPIO_DIP_SW7 SW2.9Reset Pushbutton SwitchAV40 CPU_RESET SW8.3Table 1-19: GPIO Connections to FPGA U1 (Cont’d)FPGA (U1) Pin Schematic Net Name GPIO PinX-Ref Target - Figure 1-21Figure 1-21: FPGA_PROG_B Pushbutton SW9UG887_c1_22_090612VCC1V8FPGA_PROG_BR424.7kΩ0.1 W5%GND12 34SW9
