Well as it is CMOS the decision level depends on VDD at that moment... and it was still rising if I understand it right... OK it's maybe not quite so straighforward but maybe that's the mechanism of "lockup"... I am just guessing, but if you want to be sure, ask Philips :-> Well it's still a good idea... I'll try and filter this glitch, see what happens... Further to what I was saying previously: after 1000s of start-ups, no failure WITHOUT using the external supervisor. Still not a great option, but that seems to be the only fix that actually works... And still not sure why it would solve the problem. Any idea from someone from Philips? Our distributor is not exactly quick to reply... Laurent |
