It does as many as you'd like.
There's a non-int part that compares the old switch image to the current
switches, and if different, restarts the timer.

In the ISR, the timer is dec'd to 0, and on rolling to 0 we update the
debounced image in ram, and set a flag to say that the switches have changed
state.  Usually I have one task that needs to be woken up when something
changed, and others that just look at the current state of the debounced
image.
