Specify this S-function drives a function-call subsystem attached to interrupt service routines
Specifies that the S-function is driving function-call subsystems
attached to interrupt service routines. This option applies only to
S-functions that have no input ports during code generation and 1
output port. During simulation, the S-function may have an input port
to provide a condition on which to execute. The output port must be
configured to perform function calls on every element. If any of these
requirements is not met, the
is ignored. Specifying this option
Informs the Simulink® engine that there is no implied data dependency involving the data sources or destinations of the function-call subsystem called by the S-function.
Causes the function-call subsystem attached to the S-function to be colored purple, indicating that it does not execute at a periodic rate.
Enables additional checks to verify that the model is constructed correctly.
The engine validates that the appropriate asynchronous rate transition blocks reside between the purple function-call subsystem. The engine also checks that period tasks exists. You can directly read and write from the function-call subsystem by using a block that has no computational overhead. To ensure safe task transitions between period and asynchronous tasks, use the
For data transfers between two asynchronously executed (purple) function-call subsystem, the engine validates that the appropriate asynchronous task transition blocks exits.
