Glossary Definition for Window Watchdog

Definition

A special subset of the watchdog timer feature found on microprocessor supervisory circuits. It is used to monitor software execution and assert a reset or an NMI if the processor gets stuck in a loop. This feature not only looks for periodic transitions on its input within a preprogrammed timeout period, but it also looks to see if there are "too many" transitions within its timeout period (window).
