Code model
The code model controls how code is generated for an application. Typically, the code model controls behavior such as how functions are called and in which code segment/section functions will be located. All object files of an application must be compiled using the same code model。

Data model
The data model specifies the default memory type. This means that the data model typically controls one or more of the following: The method used and the code generated to access static and global variables, dynamically allocated data, and the runtime stack. It also controls the default pointer type and in which data segments/sections static and global variables will be located. A project can only use one data model at a time, and the same model must be used by all user modules and all library modules in the project.

你说的是这2段么？这个不是解释Code和Data选Small, Medium, Large的作用吧。
