Design for in-system programming

摘要

There are many benefits to incorporating In-System Programming (ISP) in the development and production stages of new projects. Engineers are discovering that, like test, the features to support ISP must be designed in to enable the full benefitsof ISP. There are many issues that should be considered during the design stage. These include the tools to be used, the arrangement of the scan path, adequate power to support the programming operation, and many others. With proper attention to theinitial design, ISP can save significant time-to-market and costs.
