+Example description
+===================
+This example shows how to configure the System clock(SYSCLK) to have different
+frequencies: 20MHz, 36MHz, 48MHz and 72MHz. The SYSCLK frequency is selected by
+user in main.h file
+It shows how to use, for debug purpose, the RCC_GetClocksFreq function to retrieve
+the current status and frequencies of different on chip clocks. You can see the
+RCC_ClockFreq structure content, which hold the frequencies of different on chip
+clocks, using your toolchain debugger.
+
+This example handles also the High Speed External clock (HSE) failure detection:
+when the HSE clock disappears (broken or disconnected external Quartz); HSE, PLL
+are disabled (but no change on PLL config), HSI selected as system clock source
+and an interrupt (NMI) is generated. In the NMI ISR, the HSE, HSE ready interrupt
+are enabled and once HSE clock recover, the HSERDY interrupt is generated and in
+the RCC ISR routine the system clock is reconfigured to its previous state (before
+HSE clock failure). You can monitor the HSE clock on the MCO pin (PA.08).
+
+Four LEDs connected to the GPIO_LED Pin 6, Pin 7, Pin 8 and Pin 9 are toggled
+with a timing defined by the Delay function.

+Hardware environment
+====================
+This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
+boards and can be easily tailored to any other hardware.
+To select the STMicroelectronics evaluation board used to run the example, uncomment
+the corresponding line in platform_config.h file.
+
+ + STM3210B-EVAL 
+    - Use LD1, LD2, LD3 and LD4 leds connected respectively to PC.06, PC.07, PC.08
+      and PC.09 pins
+ 
+ + STM3210E-EVAL
+    - Use LD1, LD2, LD3 and LD4 leds connected respectively to PF.06, PF0.7, PF.08
+      and PF.09 pins
+      
+   
+How to use it
+=============
+In order to make the program work, you must do the following :
+- Create a project and setup all your toolchain's start-up files
+- Compile the directory content files and required Library files :
+  + stm32f10x_lib.c
+  + stm32f10x_gpio.c
+  + stm32f10x_rcc.c
+  + stm32f10x_nvic.c
+  + stm32f10x_flash.c
+  
+- Link all compiled files and load your image into target memory
+- Run the example
