pcm3168a Audio Data Format: 24-Bit TDM Format

Dear,

i have custom board has pcm3168. i can configure i2s line in 24 bit TDM(i2s single mode.) my signals is below. 

i2s through to pcm3168 is ok. and it plays sound. (in the dac side.)

so in the adc side i can not handle dout singnal from pcm3168. i think my clock signals is correct according to page 25 of pcm3168a datasheet.

the registers i set is:

// dac configurations:

pcm3168_write(codecNo,0x40,0xc1);

pcm3168_write(codecNo,0x41,0x06);

// adc configurations:


pcm3168_write(codecNo,0x50,0x01);

pcm3168_write(codecNo,0x51,0x06); 

Note: in the Audio Data Format: 24-Bit I2S(Figure 35.)  adc is working. i can get din signal. 

my problem is in the TDM farmat. 

Thanks.
