Assuming that
- Initially, you set the pin.
- You clear the pin when the M
be set ,but it was really not a wake up situation.
Did I make myself clearly? Or I misunderstanded something?
Thanks a lot.

Since this is very time critical, I would set the port values
directly. Port A2 is the red led, that's a good point to start with.
See chapter 13 in the atmega1281 datasheet.

Hi all:
Now I am analysing the atemga1281 sleep and active time on tinyos-2.x
platform,and I find a method in a paper using Oscilloscope: an output pin was
turned on in each ISR when the processor woke up from a sleep mode,the
TOSH_run_task() function turned off the output pin before executing
