[Tinyos-help] Interrupt length (time)

[Michael Schippling]

Wow...this took some research time...but I think I found interesting stuff 
in the ATMEGA specs in the External Interrupts section on pages 86-87.

 From my reading, a level triggered int needs to last for 1 micro-sec,
and/or at least one instruction cycle. You may want to do your own
hermeneutics as I didn't read all that carefully. And an edge triggered
int needs a 50 nano-sec pulse.
