Can we use INPUT_PULLUP on many pins in the same time ?

If I have 3 buttons, can I use INPUT_PULLUP on all 3 pins in the same time?

pinMode(8, INPUT_PULLUP); pinMode(10, INPUT_PULLUP); pinMode(12, INPUT_PULLUP);

or we can use only 1 pin. Tried search google but not found a document.

If I have 3 buttons, can I use INPUT_PULLUP on all 3 pins ?

Yes.

.

Every pin has its own separately controlled pullup (at least on most Arduinose, like Uno/Nano/Mega/Due...)

OK. But except for those AtMegaa328p boards which expose A6 and A7 http://forum.arduino.cc/index.php?topic=123176.0
