2.2. Setting the peripheral enable switches
The peripheral enable switches on S1 enable the buffers and
interface logic on the Interface Tile. Disabling a peripheral allows
the Versatile Logic Tile signals associated with that peripheral
to be used on the prototyping area.
Note
The camera interface does not have isolation logic. Remove
the camera module from the Interface Tile to isolate the camera signals
from the tile signals.
