1, When set enables a Watchdog timer reset.

2, Watchdog timer:Can generate a system reset or IRQ 15.

3, The software techniques include digital filtering, watchdog timer and program trap setting.

4, WDT: Watchdog timer refresh.

5, If the software crashesor hangs, the watchdog timer will expire,(http:///watchdog timer.html) and the entire system will be reset automatically.

6, A watchdog timer can automatically reset the system or generate an interrupt should the system stop due to a program bug or EMI.

7, A watchdog timer and its prescaler are also provided to improve the microcontroller anti-interference ability.

8, A watchdog timer is employed on the secondary side to look for the refresh pulse.

9, A ASK frame re-transmission principle and software watchdog timer (soft WDT) are proposed in order to guarantee steady data transmission in a wireless environment.

10, Liuzhou excellent FS2410 source board watchdog timer, reset timer can be achieved, development platform for ADS1.2.

11, Compare to traditional immovable watchdog timer, this thesis provides a method to realize alterable watchdog timer. By using this method, the chip can be applied in a broader field.

12, A hardware timer that is periodically reset by software. If the software crashesor hangs, the watchdog timer will expire, and the entire system will be reset automatically.
