Stateflow User's Guide

Defining Implicit Events

Stateflow defines and triggers the following events that typically occur whenever a chart executes:

• Chart waking up
• Entry into a state
• Exit from a state
• Value assigned to an internal (noninput) data object

These events are called implicit events because you do not have to define or trigger them explicitly. Implicit events are children of the chart in which they occur. Thus, they are visible only in the charts in which they occur.

Use the following topics to understand implicit events:
