Configuration PCI Express Switch (DS-P)

The link width and transfer rate of the PCI Express interfaces attached to the local expansion

connector P-PCIE is configurable by two DIP switches (DS-P) located on the backside of the

SC3-LARGO. Note that changes in PCIe link configuration are honoured by the board not before a

system reset was performed.
