This is the 1st topic in this forum
But anyone hasn't gave an answer

Hey RKSK, Thanks for reminding about this old topic. I have no idea how me and Magneto missed it (I'm sure this is due to one of our email subscription failures those days).

So let's talk about widely used Watchdog timers in embedded systems.

See What is a Watchdog timer in embedded systems.

Some note to Neo's article

Watchdog timer is very useful in low power mode operations also. In lots of processors , watchdog timer is the
only timer , which is working in low power modes. So you can use the watchdog timer interrupt for wake the processor
from sleep mode.
