TAS5768M ,Unexpected mute after changong MCLK

Other Parts Discussed in Thread: TAS5768M

Hi,

The stop of sound response has occurred after POR in our test.
And it is recovered by configuring register again.

It is the three following points to like to check.
1)What is the correct sequence to set register by I2C after power-on reset like Fig33 as below D/S?

Figure 33. Power-On Reset Timing, DVDD = 3.3V

2)Is it acceptable to input I2S clk and data when programming register data by I2C?
I believe in it is no matter that these data input of I2C and I2S source to the TAS.

3)
The SCK(=MCLK) may change to unexpected timing.
Then does timing cause a problem which stop the output of Amp in during a setting period?
For example, an error is detected and it carries out mute compulsorily.

best regards,

kyt
