Do the Freescale KL03 Open Drain pins support voltages above Vdd?

The datasheet suggests there is nothing special about the two open-drain GPIO's (PTB3 & PTB4) but many devices allow open-drain pins to support voltages above Vdd without damage. For example, if Vdd=1.8V can PTB3/PTB4 be driven to 3.0V? I was wondering if there was any secret knowledge surrounding these pins that would help here.

 

Thanks,
