Notes:
1. The Interrupt pin from the audio codec can connect to any available Jetson Orin NX GPIO. If
the pin must be wake-capable, choose one of the GPIOs that supports this function.
2. I2C2 supports 1.8V operation since the interface is pulled to 1.8V through 4.7 kΩ resistors on
the module. If another I2C interface on Jetson Orin NX is used, a level shifter will be required
as all the others are 3.3V.
