open drain tolerance

Hi Everyone!

I would like to know what voltages could be tolerated by the PSD module when configured as open drain output. Ie. how high can the port pins be pulled up? I'm specifically referring to pin PC7.

Also, the reset state of the port pins are CMOS (push/pull) input. Isn't it dangerous when the hardware is connected in an open drain configuration which may be pulled to a voltage rail incompatible with the PSD module?

Thanks
