Does ADAU1701 have a watchdog? How do you recover from a crash?
I'm working on a project with a fellow engineer who won't build anything without a watchdog timer. So he has his PIC microcontroller looking for a 1 Hz oscillator programmed in our ADAU1701, routed…
I did encounter repeated crashes. It was apparently due to excessive radiated noise from a nearby switching supply. Of course, this had to be mitigated, but I believe in solving every problem twice if possible. I've also asked for the board to be relaid with a complete ground plane. Have you had other reports anything like this?
