Hello,

I confirmed that the correct recommendation is tying the PCIe voltage pins (PCIE_VP,PCIE_VP_RX,PCIE_VP_TX, PCIE_VPH,PCIE_VPH_RX,PCIE_VPH_TX, PCIE_REXT) tie to ground, as per Table 5 of the Datasheet.

It will be fixed on the next release of the documentation.Sorry for the inconvenience may cause.

Best regards
