From the point of view of embedded systems, a watchdog is a device which monitors a system and is able to restart the system if or when something goes wrong. STM32 MCUs are equipped with two watchdogs: the Independent Watchdog (IWDG) and a Window Watchdog (WWDG). These watchdogs will be described in the following sections.
Independent Watchdog (IWDG)
The IWDG is, as the name implies, an independent device which watches over the MCU. It can be illustrated like this:
In the STM32, the IWDG is built-into the MCU itself.
