I2S_ENABLE port on ACEV-1A EVM

Other Parts Discussed in Thread: TLV320AIC3110

Hello, I'm Leonardo from Argentina. I buy a TLV320AIC3110 evaluation board becouse I would like to use this chip for a project.

I want to connect my uC (stm32f411, sorry!) to the audio dac by I2S, but I don't know how to disable TAS1020BPFB chip. I see that there is an input port called I2S_ENABLE that is connected to P1.2. But I can't finde any explanation about this pin functions.

Is there a way to disable I2S on TAS1020?

Thk and br!
