Abstract
A wide variety of current embedded microcontrollers like 8,16 and 32-bit of Freescale Micro Control Unit(MCU) performance is stable and various. Mc9s12xs128 is a kind of Freescale 16-bit microcontroller. The concept of the Freescale Microcontroller Minimum System and the principle of realization is systematically elaborated. Many peripheral module such as Serial Communication, Liquid Crystal Display(LCD), keyboard scanning and Digital Tube Display are developed after a thorough understanding of the basic theory of Minimum System. In addition to this work, a very detailed description of each module's hardware design and software programming methodology is also made to show that an embedded system can achieve a specific function.
