       8              ;//
       9              ;// For these examples, code_start is the first code that is executed after
      10              ;// exiting the boot ROM code. 
      11              ;//
      12              ;// The codestart section in the linker cmd file is used to physically place
      13              ;// this code at the correct memory location.  This section should be placed 
      14              ;// at the location the BOOT ROM will re-direct the code to.  For example, 
      15              ;// for boot to FLASH this code will be located at 0x3f7ff6. 
      16              ;//
      17              ;// In addition, the example DSP280x projects are setup such that the codegen
      18              ;// entry point is also set to the code_start label.  This is done by linker 
      19              ;// option -e in the project build options.  When the debugger loads the code,
      20              ;// it will automatically set the PC to the "entry point" address indicated by
      21              ;// the -e linker option.  In this case the debugger is simply assigning the PC, 
      22              ;// it is not the same as a full reset of the device. 
      23              ;// 
      24              ;// The compiler may warn that the entry point for the project is other then
      25              ;//  _c_init00.  _c_init00 is the C environment setup and is run before 
      26              ;// main() is entered. The code_start code will re-direct the execution 
      27              ;// to _c_init00 and thus there is no worry and this warning can be ignored.
