5.1.6 Disable Video Processor with JP1
When a jumper is plugged onto JP1, then the video processor is de-selected. This feature has been
implemented so that an external video processor can access the video input port of Ravin-E. JP1 is
normally not used. Therefore the board is shipped without this jumper and thus the video processor is
enabled by default.

5.1.7 Select CS input with JP2
The host connector CN1 carries two chip select signals, which can be alternatively used to select
Ravin-E. JP2 selects the active CS signal.
