Enums of smaller data types

Hi everyone,

I am wondering if there's a way to create enumerated types of smaller sizes. When generating code with Simulink models that use enums, "IntEnumType" gets cast as a machine-sized Int, in my case a 4-byte value. It takes up a lot of memory especially when you consider most of the enums only have a small number of values. Is there an easy way to avoid this?

Thanks!

• Define the class as a subclass of Simulink.IntEnumType. You can also base an enumerated type on one of these built-in integer data types: int8, uint8, int16, uint16, and int32.
