This is done by setting the clock source and using divider/multiplier ratios. This example demonstrates the following features of the RCCU : - Configuration of MCLK, FCLK, PCLK, RCLK source, PLL . Directory contents ================== scat.scf Scatter file 71x_conf.h Library Configuration file 71x_it.c Interrupt handlers main.c Main program Hardware implementation: ======================= This example works as standalone on the STR7-Eval board (mb393) and extra hardware implementation is not required to run the example. How to use it ============= In order to make the program work, you must do the following : - flash memory should be mapped at address 0x0 using the board H/W boot pins - Just compile and run it. - You can probe the CKOUT signal (if available) to monitor the clock signal. - CKOUT signal should be equal to 12MHz, if a 16MHz external oscillator is used.
