TLV320AIC3120: GPIO pin Voltage level

Akilarasan R
Prodigy 220 points
Part Number: TLV320AIC3120

Hi,

In our board, we are using TLV320AIC3120 Codec chip. In that we have enabled headset jack detection functionality by configuring page 0 / register 67 register and also configured Page 0 / Register 48 for INT1 generation. 

Then, we have configured Page 0 / Register 51 register to get interrupt signal at GPIO pin. I have two doubts in that

  1. What will be the voltage level of GPIO pin which will be outing the INT1 signal?
  2. What is the default INT1 state. For example, will INT1 be in high state as default and goes zero in interrupt event or how is it?
