TLV320ADC5120: About voice-activated function application

Part Number: TLV320ADC5120

Does its I2S slave mode support 3-wire digital audio interface (no MCLK required)?We want to use the GPIO1 as a interupt signal to MCU for voice-activated application.

We need two channel balance analog input so there is no any GPIO remain for voice-activated interupt signal output，So we want to check if the ADC I2S slave mode whether support 3-wire digital audio interface (no MCLK required)? If so then we can use GPIO1 for interupt.

Thanks!

    Hi

    In master mode we are going to use MCLK, but in SLAVE mode I didn't find clear instructions. Due to the special circumstances of your project, we did not find the relevant application. In order to better solve your problem, please post on the English forum to consult the product line experts and let them help you analyze how to configure it.
