What's the max. I2C interfaces voltage tolerance when the TX2 NX module is un-powered?

Hi,

In our custom board, the I2C is pulled to other supplies, and they maybe powered before the module, so what’s the maximum voltage on the I2C now?

Thanks.

It should not be supplied before module. As you can see in the power on sequence in Design Guide, carrier power rails should be ON after module.
