1.2.3 Watchdog Protection
AlphaLine display unit is guarded by a watchdog application. When the software freezes for an unknown reason,
then after a pre-programmed period, the display unit will restart itself and ensures that the display unit is functional
continuously.
Watchdog application is fed by a task with the lowest priority in a multitask environment. See Figure 13: Watchdog
Application on page 21. If one task freezes, the scheduler performs a context switch to other tasks with the same or
higher priority. This way, the task with a lowest level will not be scheduled and the watchdog will not be fed. And finally,
the watchdog will reset the processor.
