TCA9538: The status of I2C bus pin while TCA9538 is reset.

Hi all.

I would like to know the status of I2C bus pin(SDA/SCL) while TCA9538 is reset.
Is it Hi-Z or indefinite?

* Another I2C device is connected to the same bus as TCA9538,
I'd like to check if I can access it while resetting TCA9538.

Sorry, I want to get your comment as soon as possible.

Best Regards,
Sho
