Ok, here's the Mk.2: Determine the time it takes for the processor to be garaunteed to have all its volatile RAM fail. Program a one-shot to that length of time. Attach an edge triggered one-shot to the processor's power pins. Then, have the processor trigger the one-shot, which will force it to power down, and stay off until all its RAM is gone. I admit it's a little short of trap doors, and before you sneer at me, consider the possibilities a bit. If it takes less time for this than the large volume of instruction cycles to clear all the RAM, then it should be worth it, right? - --Brendan - --- "Rejection out of hand of all but one's favoured alternative may cost you dearly in one way or another." -Russell McMahon -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use iQA/AwUBPWK2aAVk8xtQuK+BEQIO3gCfRNWZgN1eKn6AjD/dZruz2lllwI4AoJfs 7FANypv2IvEp8Hu88X/8RmjY =jGHf -----END PGP SIGNATURE----- -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
