I am trying to figure out the proper way to hook up a reset button to the 84, according to the datasheet it needs 0.2v to 0.9v to trigger a reset, so should I just put a proper sized resistor between 5v rail, momentary button, and the reset pin?

If that is the case then how come the attiny84 runs fine with the reset pin floating, would that not then cause it to be stuck in reset and never run?
