The Research on the structure and configuration of MCU clock system for Kinets series

Kinetis L-series MUC clock system includes the clock source mechanisms such as the internal reference clock source, frequency-locked loop FLL, oscillator OSC, real time clock RTC, and provides many clock models to provide technology foundations to many low power applications, and has the features such as low power consumption, multifunction, and high performance. By the analysis of K60 clock system working mechanism, test of the clock and focusing on the analysis of the operation mechanism of the multifunctional clock generator, and puts forward the test methods of clock source performances required during the relevant chip application and design process of Kinetis and the select methods of clock sources of each functional module of the chip systems.
