Assigning I2S pins to Am335x

In my Am335x board we must use I2S Audio peripheral.
In Starter kit is used MCASP1 channel, but I need to use RMII and some pins are shared,

so I can't use MCASP1, but MCASP0.

I made comparation with starter kit and connected:

AUD_BCLK ---> A13

AUD_FSX ---> B13

AUD_DIN ---> C12

AUD_DOUT ---> D12

For first three I think that are OK because are the same name signals (MCASP0 vs MCAS1), but I am not sure for last (AUD_DOUT)

Practically,  I am not sure if I can take for AUD_DIN or AUD_DOUT any od MCASP0_AXR0,.....MCASP0_AXR3.

Could you confirm my decision. ?
