The Watchdog Timer is a fail/safe function used to reset a system in case the microprocessor gets lost due to address or data errors. The Watchdog Timer module is a 16 bit down counter with a ...

A clock circuit that keeps counting from a set number down to zero. If the event it is monitoring occurs before it reaches zero, it resets to the starting number and starts counting down again.

A watchdog is used in systems to prevent system lockup due to software or hardware failures. For normal operation, the timeout counter has to be reset by the CPU in a regular interval. Depending on ...

Small, limited-function ICs, such as watchdog timers, can make the difference between fairly good performance and solid system behavior. In many designs, the differentiator between a circuit that ...
