Can Kinetis I2S do "DSP Mode"

Hi All,

 

I need to interface to a GSM modem which has an I2S audio interface - but the device implements "DSP Mode" only. That is to say, it uses an additional clock cycle to pulse the frame sync, then the following 16 cycles are used to clock the data. The interface does not toggle the Left / Right bit like standard I2S.

 

Thanks,

All the best,
