;-----------------------------------------------------------------------------
; 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.

; Naming covention of labels in this file:
;
; ?xxx - External labels only accessed from assembler.
; __xxx - External labels accessed from or defined in C.
; xxx - Labels local to one module (note: this file contains

// Where _y can be one of:
//
// _AN -- Holds uninitialized located objects, i.e. objects with

// Segment placement - General information
//
// All numbers in the segment placement command lines below are interpreted
// as hexadecimal unless they are immediately preceded by a '.', which
// denotes decimal notation.
//
// When specifying the segment placement using the -P instead of the -Z
// option, the linker is free to split each segment into its segment parts
// and randomly place these parts within the given ranges in order to
// achieve a more efficient memory usage. One disadvantage, however, is
// that it is not possible to find the start or end address (using
// the assembler operators .sfb./.sfe.) of a segment which has been split
// and reformed.
//
// When generating an output file which is to be used for programming
// external ROM/Flash devices, the -M linker option is very useful
// (see xlink.pdf for details).
