cy8c6xx6_cm0plus.icf

/*******************************************************************************
* \file cy8c6xx6_cm0plus.icf
* \version 2.91
*
* Linker file for the IAR compiler.
*
* The main purpose of the linker script is to describe how the sections in the
* input files should be mapped into the output file, and to control the memory
* layout of the output file.
*
* \note The entry point is fixed and starts at 0x10000000. The valid application
* image should be placed there.
*
* \note The linker files included with the PDL template projects must be generic
* and handle all common use cases. Your project may not use every section
* defined in the linker files. In that case you may see warnings during the
* build process. In your project, you can simply comment out or remove the
* relevant code in the linker file.
