I'm trying to implement such as watch dog program, and I know STM32 supports 2 kind of function.
the name of IWDG and WWDG. But I just needed such as simple watch dog(under 40KHZ), so I just planned with IWDG.
but I heard that the IWDG's purpose is system reset. but I just want to check whether something signal toggled or not in the given time. what if it does not toggled in the given time then just want PA0 is active high, not want to reset. but If I use IWDG, then I think my system will be have a system reset . But I don't it. So.
So If I want to heck this function, what am I supposed to do ?
