//  Ver | dd mmm yyyy | Who  | Description of changes
// =====|=============|======|===============================================
//  1.00| 11 Sep 2003 | L.H. | Changes since previous version (v.58 Alpha)
//      |             |      | Added BEGIN section to the start of H0
//      |             |      | Removed .bss, .const and .sysmem
//      |             |      |    These are for a small memory model.  All examples
//      |             |      |    use the large model.
//      |             |      | Added .esysmem section
//      |             |      | Changed ramfuncs section to load and run from RAM
//      |             |      |    (previously this was type DSECT)
//      |             |      | Moved peripheral register files to DSP28_Headers_BIOS.cmd
//      |             |      |    and DSP28_Headers_nonBIOS.cmd
//      |             |      | Added CSM_RSVD memory section in FLASHA - this region
//      |             |      |    should be programmed with all 0x0000 when using the CSM

/* ======================================================
// For Code Composer Studio V2.2 and later
// ---------------------------------------
// In addition to this memory linker command file, 
// add the header linker command file directly to the project. 
// The header linker command file is required to link the
// peripheral structures to the proper locations within 
// the memory map.
//
// The header linker files are found in <base>\DSP281x_Headers\cmd
//   
// For BIOS applications add:      DSP281x_Headers_nonBIOS.cmd
// For nonBIOS applications add:   DSP281x_Headers_nonBIOS.cmd    
========================================================= */

/* ======================================================
// For Code Composer Studio prior to V2.2
// --------------------------------------
// 1) Use one of the following -l statements to include the 
// header linker command file in the project. The header linker
// file is required to link the peripheral structures to the proper 
// locations within the memory map                                    */

/* Uncomment this line to include file only for non-BIOS applications */
/* -l DSP281x_Headers_nonBIOS.cmd */

/* Uncomment this line to include file only for BIOS applications */
/* -l DSP281x_Headers_BIOS.cmd */

/* 2) In your project add the path to <base>\DSP281x_headers\cmd to the
   library search path under project->build options, linker tab, 
   library search path (-i).
