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 indicated for I2S[1:0]_DOUT and _DIN are associated with their use as I2S data lines. The direction for GPIO09 is
associated with its use as Audio Clock. The pins support GPIO functionality, so support both input and output operation
(bidirectional).
