碩士 === 中華大學 === 電機工程學系碩士班 === 90 === The main goal of this thesis is to explore the problems of UART ISP in microcontroller. UART ISP microcontroller manufactures, which are unable to apply the fixed ISP program on single production line, have to design different production line according to differenet customers demand. This causes the increase in the production cost. In order to improve this problem ,we use the concept of statistical distribution and the smart UART ISP design which is made of the finding to the frequency of crystal program using in application system , the download program and so on. Furthermore,this thesis also proves that most of different frequency of crystal can achieve the best situation in transmission rate via this design to save time and reduce cost.
