Here is A2B AD2428W block diagram as below,
Master side : I2S input to CPU (from salve PDM MIC)
Master side : I2S otuput to Slave node for speaker out
Can they use the same BCLK and Sync?
Slave side :PDM MIC input through PDM channel
Salve side : I2S output to audio AMP for speaker output.
Is the connection correct?
