SPORT of ADSP-21489 on packed I2S (TDM) mode with bad BCLK

Hi,

I use the DSP's SPORT with Packed I2S mode on slave status. 

I have troubles on that DSP, and i found some of them might be made by bad BCLK.

Of caurse, I will fix the waveform of it but I want to know that 2 point to isolate whether those phenomenon is due to BCLK.

 

1st,

If more than the specified BCLK is detected in one cycle of LRCLK and a lot of Bit data is read, is there a possibility that the extra Bit data will be written to the adjacent register or buffer?

 

2nd,

Can audio abnormal BCLK make bad effect to non-real-time processing?
