I have question about connection between UC3A0512, UC3C164C and TLV320AIC23. I want to control TLV registers (for example power control, microphone boost etc.) by UC3C164C and get i2s data from TLV to UC3A0512. Is it possible? I attached picture what I want to do.

Yes, it is possible.
Put pullup-resistors on the SCLK ans SDIN lines and connect the MODE pin to ground. (see datasheet)

Do you know if it is possible to READ tlv320aic23 registers? Documentation doesn't mention about it. In ASF file (tlv320aic23.c) they read register from the previous written setting not reading register by i2c.

I've tried to read TLV's registers but I'm getting error i/o. Write is ok.

from datasheet 'Control Interfaces ... 2-Wire'

The TLV320AIC23 is a write only device and responds only if R/W is 0
