The Data type replacement parameter specifies whether the generated code uses built-in C data types, C data types with fixed-width integers, or type definitions from the MathWorks^® header file rtwtypes.h.

Settings

Use built-in C data types: The code generator uses built-in C data types. This value is the default value.
Use C data types with fixed-width integers: The code generator uses data types from the C/C++ language standards, which include definitions from cstdint and stdint.h.
Use coder typedefs: The code generator uses predefined data types from rtwtypes.h.
