9;* Linker file for the ARMCC.
10;*
11;* The main purpose of the linker script is to describe how the sections in the
12;* input files should be mapped into the output file, and to control the memory
13;* layout of the output file.
14;*
15;* \note The entry point location is fixed and starts at 0x10000000. The valid
16;* application image should be placed there.
17;*
18;* \note The linker files included with the PDL template projects must be
19;* generic and handle all common use cases. Your project may not use every
20;* section defined in the linker files. In that case you may see the warnings
21;* during the build process: L6314W (no section matches pattern) and/or L6329W
22;* (pattern only matches removed unused sections). In your project, you can
23;* suppress the warning by passing the "--diag_suppress=L6314W,L6329W" option to
24;* the linker, simply comment out or remove the relevant code in the linker
25;* file.

45; The defines below describe the location and size of blocks of memory in the target.
46; Use these defines to specify the memory regions available for allocation.
47
48; The following defines control RAM and flash memory allocation for the CM4 core.
49; You can change the memory allocation by editing RAM and Flash defines.
50; Note that 2 KB of RAM (at the end of the SRAM) are reserved for system use.
51; Using this memory region for other purposes will lead to unexpected behavior.
52; Your changes must be aligned with the corresponding defines for CM0+ core in 'xx_cm0plus.scat',
53; where 'xx' is the device group; for example, 'cy8c6xx7_cm0plus.scat'.
