Are all the reset pins of the multiple processors then connected in paraller to the one output of the supervisor?
I am "butting" a lot, but (here we go again) if the processors are capable of output of reset (some/all? Cygnal processors, some Philips) you need a 1k in series with the reset pin of each processor if the reset out is Push Pull. If the reset out of the processor AND the supervisor is resistive pullup (open collector/open drain) you must connect directly. If this is not clear from the datasheet, you must ask the manufacturer. I have never tried a mix so I can not state a problem not doing this, but I Always use a supervisor that match (OC/PP) the reset circuitry of the processors. Erik |
