Triple Staged Watchdog Timer
A watchdog timer (or computer operating properly (COP) timer) is a computer
hardware or software timer that triggers a system reset or other corrective action if
the main program, due to some fault condition, such as a hang, neglects to regularly
service the watchdog (writing a “service pulse” to it, also referred to as “kicking the
dog”, “petting the dog”, “feeding the watchdog” or “triggering the watchdog”). The
intention is to bring the system back from the nonresponsive state into normal
operation.
The COMe-bEP7 offers a watchdog which works with three stages that can be
programmed independently and used one by one.
