Use an external countermeasure such as muting until data is set. • When performing initial setting after applying power, send the initial setting data for the left and right channels prior to canceling mute. • To ensure that the high-frequency digital signals sent to the CL, DI, and CE pins do not spill over to the analog signal block, either guard these signal lines with a ground pattern, or perform transmission using shielded wires.
