Figure 9–24. Transitions between Configurations in Remote Update Mode
After power up or a configuration error, the factory configuration logic is loaded
automatically. The factory configuration also specifies whether to enable the user
watchdog timer for the application configuration and if enabled, to include the timer
setting information as well.
The user watchdog timer ensures that the application configuration is valid and
functional. The timer must be continually reset in a specific amount of time during
user mode operation of an application configuration. Only valid application
configurations contain the logic to reset the timer in user mode. This timer reset logic
must be part of a user-designed hardware and/or software health monitoring signal
that indicates error-free system operation. If the timer is not reset in a specific amount
of time; for example, the user application configuration detects a functional problem
or if the system hangs, the dedicated circuitry updates the remote system upgrade
status register, triggering the loading of the factory configuration.
The user watchdog timer is automatically disabled for factory configurations. For
more information about the user watchdog timer, refer to
page
9–54.
