Notes:
1. The Interrupt pin from the audio codec can connect to any available Orin module 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 2.2 sistors on
the module. If another I2C interface on Orin module is used, a level shifter will be required as
all the others are 3.3V.
