<fontfamily><param>Arial</param>Does anyone know of a small code to

; OK I am being a wise-ass but I couldn't resist :)

; actually the above is a restart rather than a reset

; There is more to this question than meets the eye - 

; you could also initialize all SFRs to their POR values

;

; internal RAM will be random, unless you want to clear it

; initialize the SP (stack pointer)

; init interrupt states (priority, enabled or not, edge/level, etc)

; Actually if your startup code properly inits all things, then

; a branch to 0 should be fine

;

; Many or most people don't have their firmware set things to the state

; they would be in after a power up

; Depends what you are trying to do and what your SW reset needs to do
