    Hi,

    By default the device is in slave mode. You can configure the device to be master by changing the direction of BCLK and WCLK using the register below.

    Hi,

    By default slots 1 and 2 will be used by the codec. You can move these by using the offset selection register.

    For example if I am using TDM8 with 16 bit depth, normally the codec is listening on slots 1 and 2. I can move this to slots 3 and 4 by adding a 32 bit offset (16 * 2 = 32) programmed to register 0x1C.

    Registers below program which inputs are connected to the left PGA. You can select the sources that you want to be mixed here. For example since you have IN2L_P used as a mic, you can use bits D5-4 to connect that input to the left PGA. 

    Likewise, IN2R can be connected to the right side for the other mic.

    Best regards,
