; This file contains the startup code used by the ICCARM C compiler.
|
||||
;
|
||||
; The modules in this file are included in the libraries, and may be replaced
|
||||
; by any user-defined modules that define the PUBLIC symbol _program_start or
|
||||
; a user defined start symbol.
|
||||
; To override the cstartup defined in the library, simply add your modified
|
||||
; version to the workbench project.
|
||||
;
|
||||
; All code in the modules (except ?RESET) will be placed in the ICODE segment.
