Programming Via the Bootstrap Loader The MSP430BSL enables users to communicate with embedded memory in the MSP430microcontroller during the prototyping phase,final production,and in service.Both the programmable memory(flash memory)and the data memory(RAM)can be modified as required.Do not confuse the bootstrap loader with programs found in some digital signal processors(DSPs)that automatically load program code(and data)from external memory to the internal memory of the DSP.These programs are often referred to as bootstrap loaders as well.

To use the bootstrap loader,a specific BSL entry sequence must be applied.An added sequence of commands initiates the desired function.A boot-loading session can …… 此处隐藏：22952字，全部文档内容请下载后查看。喜欢就下载吧 ……
