Stateflow supports multi-word fixed point data only as inputs or outputs of a chart, a MATLAB function, or a Simulink function. As a result, data is not supported.

Stateflow supports access to multi-word fixed point variables only as inputs and outputs to nested MATLAB functions, MATLAB-based Truth Table functions, and Simulink functions. Direct access to variable in the C action language is therefore illegal in the above context
