 <documentation>About this model:
-----------------
The TimeBomb example from the video course &quot;Modern Embedded Systems Programming&quot;:

https://www.youtube.com/c/StateMachineCOM


This example demonstrates:
- Active object TimeBomb) with hierarchical state machine
- Automatic code genertation from the model
- Integration between the generated code and other code, such as the Board Support Package (BSP)


Building and running the example:
This example builds with the uVision project &quot;lesson&quot; and is designed to run on the TivaC LaunchPad board.</documentation>
