Rauf,

> So far, I haven't found any glitch!!!!

But Atmel can feel free to change it in a new stepping
without needing a new data sheet !

But be not anxious:
New developing goes in direction of more security, e.g.
brown out detection,
internal reset,
asynchronous reset (without clock source).


I use in a 15kV gadget an external reset circuit
to be real secure.
