To use tasking/threading with MC-3020, the user must mark the feature enabled providing the "flavor" of tasking/threading provided by the underlying operating system (OS) or real-time operating system (RTOS). Use the marking described the section called “Enabling Multi-Tasking”.

Once the tasking/threading capability has been enabled, the priorities of the desired tasks must be established. Various operating systems (OSes) and real-time operating systems (RTOSes) use different symbology for setting priority. For example, Nucleus PLUS uses integer numbers between 0 and 255 to indicate the priority of a task. (0 is the highest priority; 255 is the lowest.) Use the marking function described in the section called “Establishing Multi-Task Priority” to set the priority of the tasks in the xtUML generated system.

Classes must be mapped to the tasks identified with the marking functions above. Use the marking function described in the section called “Mapping Classes to Tasks/Threads” to map classes to tasks.
