Board designs for x2 and x1 must use x4 guidance. For x2 board designs, based on the controller to be used, connect to controller lane numbers Controller 0 [1:0] or Controller 1 [1:0]. Similarly, for x1 board designs, connect to controller lane numbers Controller 0 [0] or Controller 1 [0].
Note: Controller lane numbers might not be the same as physical
GTYP channel numbers in a quad. Refer the provided placement table.
