I am having trouble with the SC18IM700 on a project.
It seems to be failing for no apparent reason. It resets "itself" at random times.
I checked the signals when these resets happen, the RESET and WAKEUP pin remain high. The power line is stable as well. Even with those conditions, I can sometime see the "OK" @ 9600 bauds and the GPIOs going "up" as if they were inputs (GPIOs are pulled-up in my design).
Is there other reset conditions besides :
- - pulling down the reset pin
- - sending a "Z" commande and pulling down the wakeup pin
- - powering the device down and up again
In my case, the resets occur without any of these conditions...
Thanks for your help
