Thanks Joerg. Placing the variable in no_init is
working. I'm checking the MCUSCR in the main()
function, seems to be working fine. I can determine if
it is a power up reset or an external reset.

Arthur, you mentioned init3, maybe i shouldn't rely on
that I can check the MCUCSR in my main() function?
