PCI Express* Controller Lane Reversal
For each PCIe* Controller we support end-to-end lane reversal across the four lanes mapped to a controller for the two motherboard PCIe* configurations listed below. Lane Reversal means that the most significant lane of a PCIe* Controller is swapped with the least significant lane of the PCIe* Controller while the inner lanes get swapped to preserve the data exchange sequence (order).
- The 2x1+1x2 configuration is enabled by setting the PCIe* Controller soft straps to 1x2+2x1 with Lane Reversal Enabled
