Questions about iMX6Q ESAI TDM (network) mode external signal pins

I am trying to enable ESAI interface as TDM (network) mode for a multi-channel codec. 


I am looking at the IMX6DQRM.pdf 'Table 25-1. ESAI External Signals' as the attached images. The clock signals (CLK, FS, HF_CLK for both Tx/Rx) are very straightforward, but I can't tell which two data signals(Tx/Rx) will be used by iMX6 ESAI TDM (network) mode. 


After configured ESAI to TDM mode, will Tx/Rx data signals been fixed to specific two data signals? 
If yes, which two data signasl should I use ? 
If not, how to select them or configure them? 


Thanks for the help,
