Recently I went into a project to update a portable analyzer firmware. The processor for this project is M68HC705 and its firmware is programmed with its instructions. Although this product has very long service history but we donot want to change more because new generation high level product has been lanched.
currently my task is to understand the code and change some minor display strings, but I am not familiar motolora processor and its system. Does anyone give any suggestion or comments to me? Thanks in advance.
