I’ve seen watchdog timers mentioned in microcontroller specs. After looking into it, I’m even more confused. I get that it’s supposed to reset the system if something goes wrong, but how exactly does it work, and when is it needed? Hoping to get some clarity on this.

A watchdog timer (WDT) is a hardware timer that resets the microcontroller if it crashes or freezes. The system must periodically reset the WDT ("kick" it) to prevent a reset. If it fails, the watchdog assumes a fault and restarts the system
