MICROMONITOR RUN TIME STARTUP

The monitor breaks the target memory (flash memory and RAM) into four basic sectionsýflash memory space used by the monitor executable, flash memory space used for file storage, RAM space used by the monitor executable, and RAM space available for applications that are launched out of the file system. The entire RAM space used by the monitor (even its stack) is statically allocated within the .bss space dedicated to the monitor. All other RAM is for use by the application to execute (TFS transfers files from flash memory to RAM for execution).
