|---|---|
| PB0 | Controls the display of the Intel icon in the top right-hand corner of the output display. At startup display of the icon is enabled. Pressing PB0 toggles the enable for the icon display. |
| PB1 | Controls the scaling mode of the design. When a source or sink is hot-plugged the design defaults to either:
Each time you press PB1 the design swaps to the next scaling mode (passthrough > upscale, upscale > downscale, downscale > passthrough). . |
