; The first line specifies a preprocessor command that the linker invokes
; to pass a scatter file through a C preprocessor.
;*******************************************************************************
;* \file cy8c6xx7_cm0plus.sct
;* \version 2.95.1
;*
;* Linker file for the ARMCC.
;*
;* 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 location 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 the warnings
;* during the build process: L6314W (no section matches pattern) and/or L6329W
;* (pattern only matches removed unused sections). In your project, you can
;* suppress the warning by passing the "--diag_suppress=L6314W,L6329W" option to
;* the linker, simply comment out or remove the relevant code in the linker
;* file.

; The defines below describe the location and size of blocks of memory in the target.
; Use these defines to specify the memory regions available for allocation.
; The following defines control RAM and flash memory allocation for the CM0+ core.
; You can change the memory allocation by editing the RAM and Flash defines.
; Note that 2 KB of RAM (at the end of the SRAM) are reserved for system use.
; Using this memory region for other purposes will lead to unexpected behavior.
; Your changes must be aligned with the corresponding defines for the CM4 core in 'xx_cm4_dual.scat',
; where 'xx' is the device group; for example, 'cy8c6xx7_cm4_dual.scat'.
