2* \file cy8c6xx7_cm4.icf
3* \version 2.95.1
4*
5* Linker file for the IAR compiler.
6*
7* The main purpose of the linker script is to describe how the sections in the
8* input files should be mapped into the output file, and to control the memory
9* layout of the output file.
10*
11* \note The entry point is fixed and starts at 0x10000000. The valid application
12* image should be placed there.
13*
14* \note The linker files included with the PDL template projects must be generic
15* and handle all common use cases. Your project may not use every section
16* defined in the linker files. In that case you may see warnings during the
17* build process. In your project, you can simply comment out or remove the
18* relevant code in the linker file.
