I have never used external RAM before (beleive it or not :-o ) . Now I am using an NVRAM from Dallas so that in case of power failure the value of some variables is retained. My question is how do I declare the 'Non Volatile External' variable and how do I retreive the previous (pre-power fail) value ?
