In state actions (entry, during, exit, and on event_name) and transition actions, use the send command to broadcast explicit events. Using this command enhances readability of a chart and ensures that explicit events are not mistaken for data.

If you have multiple charts in your model, avoid defining events where the parent is the Stateflow machine. If you broadcast an event to all charts in your model, the order in which the charts awaken is unknown.

If you mix input events that use edge triggers and function calls, the chart detects this violation during parsing or code generation. An error message appears and chart execution stops.

Use the in operator instead of the enter implicit event to check state activity. See Checking State Activity for details.
