OR-ing DIO0, DIO1 and DIO2

[i-g-g-y]

Hello.

Questions:

• is it possible to OR to a single pin DIO0, DIO1 and DIO2?
• Are they active high or active low?
• are they of the same polarity, e.g. all active high or all active low?
• is it possible to OR any combination of DIO0, DIO1, DIO2?

Thanks,
Iggy
