Tenda AP4 User Manual

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