    hello Ray,

        GDE is old GUI. The Q factor calculations between PPC1 and GDE seems different.

    We had talked with software team to double check this case. we will confirm back.

    Hi Ray,

    OSC trim register is used for initial, and the reserved and trim done value changes after initialization.

    Modulation limit register is manually changed. At my side EVM test, the read back value is default 0x02. It's suggested to set 0x07 with PVDD > 18V situation.

    Other EQ and DRC parts are low bits of configuration registers caused by DSP structure. They can be ignored.

    So Write I2C Init File dump out script can be used for system integration.

    Regards,

    Matthew
