The program module xllp_CPUfreq.s, xllp_freq.c, xllp_intc.s, xllp_freq.h four documents is to modify the main CPU frequency code before they can be used xllp directory files and compiled files together so that you can program call them from anywhere, modify, and read the CPU frequency mainly rely on call xllp_freq.c document the completion of two functions: XLLPSetCoreRunFrequency, xllpGetCurrentFreqSetting. The remaining code is just a call to an example of these two functions, you can re-write one himself. If the sake of simplicity, all files can be used as a driver in the same directory to compile and then load the stream-driven manner, and then application control.
