We would like to test I2S audio with modul Cinterion PLS8-E version3 with Cinterion DSB mini board + Cinterion multi adapter. We need know exact pins dedicated for I2S digital audio. From documentation  (M2M-accessories-dsb-mini_ug.pdf) on page 22, I found description i2s pins on DAI connector.

I2S_OUT is probably pin3 DAI1/TX

I2S_IN is probably pin4 DAI1/RX

I2S_CLK is probably pin6 DAI3/BITCLK

however I don’t know which pin is I2S_FSC (frame synchr). Is it pin5 DAI2/FS or pin7 DA4/FSIN? I marked it bellow picture with yellow colour.

Thank you in advance
