USB-8451 pull up resistor

Dear all,

I'm using the 8451 as i2c master, and for some reason (not important for this discussion) I need to use one of the 8451 pins as a 3.3V voltage source.I chose a DIO pin for the job and with Labview I managed to configure it properly to 3.3v with "push pull" driver type. My question is if there's an internal pull up resistors and if so, how could I configure it?

Thanks,

Or
