Autoinitializing variables at run time is the default method of autoinitialization. To use this method, invoke the linker with the --rom_model option.
Using this method, the linker creates a compressed initialization table and initialization data from the direct initialized sections in the compiled module. The table and data are used by the C/C++ boot routine to initialize variables in RAM using the table and data in ROM.
Figure 6-3 illustrates autoinitialization at run time. Use this method in any system where your application runs from code burned into ROM.
