Hi

To verify that the TLV320ADC3120 is configured as an I2S master, using the TDM protocol and connected to two microphones, register configuration is required.

    w 98 01 01 # Software Reset
    d 100 # Delay 100ms
    w 98 00 00 # Select Page 0
    w 98 02 81 # Wake up device and enable AREG
    d 10 # Delay 10ms
    w 98 07 30 # 32 bit TDM
    w 98 0b 00 # Channel 1 to slot 0
    w 98 0c 01 # Channel 2 to slot 1
    w 98 13 82 # Master mode
    w 98 3c 00 # Channel 1 differential, AC coupled microphone input
    w 98 41 00 # Channel 2 differential, AC coupled microphone input
    w 98 74 c0 # Enable output channel 1 and 2
    w 98 76 e0 # Power up ADC, MICBIAS, PLL

    Best,
