> Who cares what's on the stack after a 'reset'? > D Since the SP does not get reset (Bob says it does not matter since it is circular), you do, since you may run out of free stack sooner than you plan. F.ex. if the stack is not circular and the soft reset occurs in a subr. nested at stack level 2 and the soft reset does not clear the stack (it can't, on a 12 or 14 bit core pic) then you only have 4 levels of stack left. This is almost certainly not enough. Of course the point is moot if the stack is circular but my ompression of the datasheet programs was, that it is not.
