in case of crash

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 to a GPIO pin.  If the PIC doesn't see it and times out, it resets both itself and the -1701.
