Here it describes:


The DS80C400 is equipped with a ROM (bootstrap) loader that can configure certain features of the microcontroller. It can also be used to load software into NV SRAM, which will be used as the program memory. It supports the loading of any Advanced Micro Devices flash memory device that meets the speed and size/format requirements of your specific design. Details of enabling the ROM loader in your design can be found in the High-Speed Microcontroller User's Guide: DS80C400 Supplement on page 173 (www.maxim-ic.com/MicroUserGuides.htm ).
