put a short outage on supply of different lengths simulating mains glitch. Without diode from reset to VCC across C's charging resistor, the capacitor isn't discharged fast enough for a fresh power on reset when a short power outage. Standard practice for 20 years on Industrial controller reset pins to improve reliability. -- You received this message because you are subscribed to the Google Groups "jallib" group.
