I2S Full Duplex + DMA

Hello ,

I want to configure I2s full duplex mode for  Audio Codec with SPI3 module.

As per Manual, if  I2S module is in Master TX mode , I2Sext module would be in Slave Rx mode . Now my audio codec has been configured as Slave device because of this I2Sext_SD  which is RX line is not receiving any data .

Can I config I2S  &  I2Sext in Master TX and Master Rx mode  ??

Is there any other way work-around in this scenario ?
