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.
