Application Note : Watchdog Timers (WDT)
Watchdog Timer (WDT) is an IC to monitor the proper functioning of the system with reference to detecting a timer reset by an input clock within a set monitoring period of timer.
If not being input a clock signal within the period by the system's abnormal operating, the reset signal is output. And, the WDT can detect a abnormal reduction of the supply voltage with high accuracy.
