 		 #99424 - the consensus last time was that the onl
Responding to: ???'s previous message
The consensus last time was that the only totally equivalent of a fresh start is to let a watchdog time out. Even that is not "totally" equivalent if rgere is no clear RAM routine in the startup.

What is "always" forgotten in the "do this, do that, then jmp 0" "solutions" is that the SFRs do not get reset to their reset values when such is done.

I have seen this done with "restoring all SFRs to their initial value" in the startup code, but have yet to see that without "a little glitch" partially because "you only need to restore the SFRs you use".
