+@par Example Description 
+
+This example shows how to configure the TIM9 peripheral to generate two different 
+signals with two different frequencies.
+
+The TIM9CLK frequency is set to SystemCoreClock (72 MHz), and we want to get TIM9
+counter clock at 24 MHz so the Prescaler is computed as following:
+   - Prescaler = (TIM9CLK / TIM9 counter clock) - 1
+
+The TIM9 CCR1 register value is equal to 32768: 
+CC1 update rate = TIM9 counter clock / CCR1Val = 732.4 Hz,
+so the TIM9 Channel 1 generates a periodic signal with a frequency equal to 366.2 Hz.
+
+The TIM9 CCR2 register is equal to 16384:
+CC2 update rate = TIM9 counter clock / CCR2Val = 1464.8
+so the TIM9 channel 2 generates a periodic signal with a frequency equal to 732.4 Hz.

+@par Hardware and Software environment 
+
+  - This example runs only on STM32F10x XL-Density Devices.
+  
+  - This example has been tested with STMicroelectronics STM3210E-EVAL (XL-Density) 
+    evaluation board and can be easily tailored to any development board.    
+
+  - STM3210E-EVAL Set-up 
+    - Connect the TIM9 pins to an oscilloscope to monitor the different waveforms:
+       - PA.02 (TIM9_CH1)
+       - PA.03 (TIM9_CH2)
+  
+
+@par How to use it ? 
+
+In order to make the program work, you must do the following :
+ - Copy all source files from this example folder to the template folder under
+   Project\STM32F10x_StdPeriph_Template
+ - Open your preferred toolchain 
+ - Rebuild all files and load your image into target memory
+ - Run the example 
+
+@note
+ - Low-density Value line devices are STM32F100xx microcontrollers where the 
+   Flash memory density ranges between 16 and 32 Kbytes.
+ - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
+ - Medium-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 64 and 128 Kbytes.  
+ - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx 
+   microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes.
+ - High-density Value line devices are STM32F100xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes. 
+ - High-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 256 and 512 Kbytes.
+ - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
+   the Flash memory density ranges between 512 and 1024 Kbytes.
+ - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
