Watchdog circuits, also known as watchdog timers or simply watchdogs, are essential components in electronic systems, particularly microcontrollers and embedded systems. Their primary function is to detect and recover from system malfunctions. A watchdog circuit is essentially a hardware timer that is periodically reset by the main program. If the program becomes stuck or unresponsive due to a bug, a crash, or an external interference, it will fail to reset the watchdog timer within its specified time limit.
When the watchdog timer expires, it triggers a system reset. This action is designed to bring the
The implementation of a watchdog circuit typically involves configuring a hardware timer to count down from
