WatchdogTimeouts
WatchdogTimeouts refers to the configured time window within which a watchdog mechanism must be refreshed to indicate normal operation. A watchdog timer is a hardware or software timer that runs independently from the main processor. If the monitored software or component fails to reset or “kick” the timer within the allotted interval, the timer expires and triggers a predefined action, such as a system reset, an interrupt, or an alert.
There are several implementations of watchdog timeouts. Hardware watchdog timers are built into many microcontrollers and
Configuration and behavior vary. Typical timeouts range from tens of milliseconds in fast embedded systems to
Usage considerations include tuning for reliability, particularly in safety-critical or high-availability systems. Debugging can be challenging
