    Hello customer,

    Please debug by:

    1. To confirm the I2C address
    2. Use your I2C tools to confirm whether NACK occurs during I2C communication;
      1. If your Tools cannot find NACK, then please scopes I2C waveforms to me for analysis.

    3. To share how you write this commands by capture some pictures to us.

    Regards,

    Alix Wan.

    I created a set value using PPC3
    and,I use a different writing method than PPC3

    1. I Create Settingfile(TAS.csv) with setting values written
    2. Transferring settings to devices that already have TAS5751(via USB_Memory)
    After reboot
    Some differences when reading set values from the device

    I looked for a setting that would be the value read using PPC3 but could not find it.
    What is the difference between the settings I wrote and the settings I read?
    Please tell me

    Best Regards
