    Hey Eric,

    This would still work without these. These are used if I2C is being implemented. If I2C is not being implemented it's recommended to tie SDA and SCL to VDD and /INT to GND.

    The /MICPRESENT is used to indicate to the host that the aux has been inserted. If the customer sees no use for it in their system then it won't affect the actual functionality of the device.

    Thanks,
    Rami
