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 DP_AUX_CH[1:0]_HPD is true when used for Hot-plug Detect. Otherwise, if
used as GPIOs, the direction is bidirectional.
A standard DP 1.4 or HDMI V2.0 interface is supported. These share the same set of interface
pins, so either DisplayPort or HDMI can be supported natively.
