2.9.3 Type 1 PCI Express x8 Device Layout Example
Figure 2-10 below shows an example of routing a Type 1 x8 PCI Express link from the PCIe/104 connector directly
to a PCI Express x8 device. This device is shown as a stack down version and implements lane shifting.

2.9.4 Type 1 PCI Express x16 Device Layout Example
Figure 2-11 below shows an example of the routing from the Device connector directly to a PCI Express x16 device.
This example is stack down and does not use lane shifting since the x16 device uses all of the lanes on the link.
