    Hi Stefan,

    Can you check the status XRSn pin of the device ?

    Regards,

    Hi Vivek,

     

    I measured on the XRS pin with the oscilloscope while the debugger was connected to the device.

    Here you can see the wiring diagram and my measured signal.

    I measured on the XRS pin even without a debugger attached. The signal is high until I hit the reset button (S1). Then the signal goes to low.

    The same thing happened to me a few weeks ago with another device. What could be the reason for the microcontroller to jump into the low-power mode?

    Regards,

    Stefan Mayer

    Do you have watchdog enable in your application which is causing this reset pulse ?
