Watchdog

Let's disable the house-keeper

A watchdog timer (WDT) is a hardware timer that automatically generates a system reset if the main program neglects to periodically service it. It is often used to automatically reset an embedded device that hangs because of a software or hardware fault.
A watchdog timer sometimes called a computer operating properly or COP timer, or simply a watchdog is an electronic or software timer that is used to detect and recover from computer malfunctions.
During normal operation, the application regularly restarts the watchdog timer to prevent it from elapsing, or "timing out". If, due to a hardware fault or program error, the application fails to restart the watchdog, the timer will elapse and generate a timeout signal. The timeout signal is used to initiate corrective actions. The corrective actions typically include placing the computer and associated hardware in a safe state and invoking a computer reboot.
It is recommended to disable the watchdog timer, in case of non continous use.
