    Wayne,

    As there is hardware mode and software mode selection during power up, so i would assume this time is for mode selection. After that 12ms, if SW mode is used, then IIC will be accessible.

    Matthew will feedback you with more answers and details.

    Hi Wayne,

    There is only limited material to explain this parameter, so it's also one ambiguous concept for us. Do you already meet any I2C communication error with TAS5760 software mode?

    What's more, as for hardware and software mode selection, it should be decided through SPK_GAIN pin configurations.

    Regards,

    Matthew
