Output (note)
Notes:
1. In the Direction column, Output is from Orin module. Input is to Orin module. 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 Initiator Clock. The pins support GPIO functionality, so support both input and output operation (bidirectional).
