Other Parts Discussed in Thread: TAD5242

Hello team,

How can I configure I2S master or slave for this device? Can I configure with hardware pin?

For example, TAD5242 is clear that I can configure I2S by hardware pin.

Best Regards,

    Hello Kei,

    This is mentioned in datasheet pin assignment's table. Pin 14 (MAST) in hardware mode makes the device master or slave: Connect this pin  to High and device will be in Master mode and  BCK/LRCK will be outputs, or connect MAST to LOW and device will be in Slave mode and you need to provide the clks.
