Data Transmission of Fixed Equalizer Setting
Faulty operation in the communication error occurrence.
Fixed equalizer setting premise no-change setting after setting is done once.
By this premise, A noise countermeasure circuit of the setting change isn’t built in.
Therefore, It has the possibility that noise is made by communication error.
These countermeasures are taken by this IC as it is shown in next page.

In the case of the upper figure,Fixed equalizer gain setting of FRONT Lch low range
occur faulty operation, and it has the possibility that noiseis made.
