Notes:
1. In the Type/Dir column, Output is from Jetson Xavier NX. Input is to Jetson Xavier NX. Bidir is for Bidirectional signals.
2. The direction shown in this table for CAM[1:0]_MCLK and CAM[1:0]_PWDN is true when used for those functions. These pins are
GPIOs and can support input or output (bidirectional). The direction indicated for GPIO01 and GPIO11 is associated with their use
as clock outputs.
