If no VGA display isattached, then the “Scroll or Rotate Graphic”, “Scroll or Scale Graphic”, and “RestartAutoPilot, Speaker Volume Control” modes offer little to no functionality, the exceptionbeing the volume control assuming that a speaker is attached to the audio jack.Power-Saving Suspend ModeAll of the preloaded FPGA configuration bitstreams have the power-saving Suspend modeenabled. Suspend mode reduces FPGA power consumption while preserving the presentstate of the FPGA application and the FPGA’s configuration data. Set the SUSPEND switchto RUN or SUSPEND as described in “SUSPEND Switch,” page 26.Figure 1-5: LCD Screen Output using Menu SystemPress KnobPress KnobPress KnobPress KnobStart Demonstration DesignPower-up boardPress PROG_B buttonConfig. 1Config. 2Config. 3Config. 4MultiBootMultiBootMultiBootMultiBootAutoPilotAutoPilotAutoPilotAutoPilotUG334_c1_05_052707RotateScaleVolumeSelect FPGAConfigurationSelect MultiBootScroll/Rotate GraphicScroll/Scale GraphicAutoPilot/VolumeBtns: Load Cfg 1Spin: Select CfgPress Knob 3xFor Boot MenuPress Knob 2xFor Boot MenuPress Knob 1xFor Boot MenuWelcome to XLNXS3A Starter KitWait 1 second
