Notes:
1. In the Type/Dir column, Output is from Jetson AGX Xavier. Input is to Jetson AGX Xavier. Bidir is for Bidirectional signals.
2. The direction shown in this table for PEX_Lx_RST_N, PEX_Lx_CLKREQ_N and PCIE_WAKE_N signals is true when used for
those PCIe functions. Otherwise if used as GPIOs, the direction is bidirectional.
