Notes:
1. In the Direction column, Output is from Jetson Orin NX. Input is to Jetson Orin NX. Bidir is for Bidirectional signals.
2. The direction shown in this table for GPxxx_PCIEx_RST* and GP185_PCIE_WAKE* signals is true when used for those PCIe
functions. Otherwise, if used as GPIOs, the direction is bidirectional.
The following table shows the mapping options for Jetson Orin NX.
