could you show me example how to stop or freez IWDG in STM32F407 ?
Thank you in advanced
This assumes that a running WDG can be stopped.
This assumption is wrong. Once running, you need to "feed" it constantly, or face reset.
This "feature" was/is discussed here occasionally. Perhaps a search would bring up previous, similar threads - if they didn't go lost during the Great Transition, or a former meltdown.

e.g. STM32F030, stopping the IWDG
In STOP mode, once the watchdog is started, then it cannot be stopped except by a reset. According to the reference manual RM0090 : "the IWDG is started by writing to its Key register or by hardware option. Once started it cannot be stopped except by a Reset. See Section 21.3 in Section 21: Independent watchdog (IWDG)."
Hope this helps you.

In Standby mode: once the IWDG is started, it cannot be stopped except by a reset.
