220 I2S1_DOUT GP207_DAP4_DOUT I2S Audio Port 1 Data Out Output (note)
222 I2S1_DIN GP208_DAP4_DIN I2S Audio Port 1 Data In Input (note)
211 GPIO09 GP167 GPIO #9 or Audio Codec Initiator Clock Audio Device Output (note)
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 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).
