Kinetis series of MCUs embedded the core of ARM? CortexTM-M contains a complex clock system. At the time of each functional module in the clock system which includs multi-function clock generator,phase-locked loop, frequency-locked loopand crystal vibration system, coordinated work, the clock system can provide a stable clock source for the application system. Based on the analysis of the structure and configuration method of K60 clock sys-tem and the MCG operating mechanism,the testing method of clock source performance and the clock source selec-tion method of each function modules are proposed. All of above provides references for Kinetis related chips clock system configuration in the process of application design as well as the clock source selection.
