Hi everybody,

Using the watchdog timer after the sleep mode I have come across the severe problem when the watchdog doesn't reset the MCU, if I intentionally put the forever loop in the program. It happens only after exiting the sleep. Before enetering the sleep mode the watchdog timer operates perfectly. The configuration of the watchdog timer is the same for both cases (before going to sleep and waking-up).

Why is it happenning and how can it be prevented?

I use the Scu_GoFromNormalModeToPowerSavingMode(&PowerSavingCfg) function to enter the sleep mode
