TLV320AIC34: WCLK on DSP mode

Part Number: TLV320AIC34

Hi,

Is the WCLK of the following blue line allowed on DSP mode?

I could not find the specification of the WCLK width.

I'm referring to the following application note.

    Kuramochi-san, 

    The WCLK should be the width of one BCLK period.  Other codecs in our portfolio are a little more flexible on this, using only the rising edge of WCLK to mark the frame, the AIC310x and AIC34 devices are more strict. 

    best regards,
