Your only observations were those phone calls, and your solution was to slap together a different circuit reasoning about what heppens at power on and drawing a conclusion, then implementing it, is hardly "slap together a different circuit". Reasoning is how the ancients decided that the world was flat. I appreciate that doing anything that I do not do Richards way makes me a bungling amateur, so be it. Perhaps not, but it surely suggests you're being sloppy. Once again everybody, except you have realized that a proper supervisor is mandatory for flash based circuits. apparently it's not helpful to have one with external memory, as the supervisor-generated reset doesn't prevent the corruption and signal activity I observed with the Philips, Intel, and AMD parts. Erik One of these days I'll get around to fooling with 805x issues again. I'll get some pictures and precisely monitor the voltage levels as Vcc decays. The observations I made in the past were ad-hoc, hence not sufficiently rigorous to provide any reliable information. They were enough to pique my interest, though. They involve the core reason for my decades-long avoidance of post-8048 Intel processors. I've always believed that positive reset was a mistake. That's why I've never voluntarily used an Intel MCU or CPU with positive reset in a customer's application. Occasionally I have to, but not of my own free will. RE |
