8.6.10 Hardware watch dog
This function uses an embedded watchdog timer to detect the operation condition of the device’s
main program regularly. During normal operation, the device regularly resets the watchdog timer
to prevent it from elapsing, or "timing out". If the device fails to reset the watchdog timer, due to a
hardware fault or program error, the timer will elapse and generate a timeout signal. The timeout
signal is used to reboot the device to make it recover from malfunctions.
