temp setting list below.

: write 108 0x03   //  passive analog bypass mode configuration

  • Hi Taotao,

    The bypass path is used in order to connect the input to output directly. The next picture shows in red the path that you must to use in your project if you're searching for configure the bypass path.

    Regarding the register configuration, you only need to configure register 108 (0x6C) as 3 (0x03) to use it. Register 81 and 86 can be omitted. I hope this helps you. If you still have questions or comments please let me know.

    Best regards,
