Change wakestate at every reset

I've just finished a little writeup of the project I concluded this weekend. A hardware mod to enable the possibility to change wakestate at every reset instead of hoping for it to change to what you want by endless power cycling.

(I don't really expect that many people to be interested, but for someone like myself that want to test code and do logic analyzer captures of all different wakestates often this will save a huge amount of time!)

Thanks to Ijor for the theory. This is what my implemented schematics looks like (Eagle file downloadable from my blog)

Heh, thanks - it's nowhere near the stuff you're doing, but it's at least a baby step for someone like me who's never done any micro electronics ;) I installed Eagle yesterday ...

At least your doing something constructive, matters not big or small project, its progress into understanding the world and the universe and everything in it.. :thumbup:
