+@par Example Description 
+
+This example shows how to configure external interrupt lines.
+In this example, 2 EXTI lines (EXTI0 and EXTI8 or EXTI9) are configured 
+to generate an interrupt on each rising or falling edge. In the interrupt routine 
+a led connected to a specific GPIO pin is toggled.
+
+In this example:
+  - EXTI0 is mapped to PA.00
+  - EXTI8 is mapped to PG.08
+  - EXTI9 is mapped to PB.09
+
+After EXTI configuration, a software interrupt is generated on the EXTI0 toggles LED1.
+After that,
+  when rising edge is detected on EXTI0, LED1 toggles
+  when falling edge is detected on EXTI8, LED2 toggles
+  when falling edge is detected on EXTI9, LED2 toggles
+
+
+If any STM3210XX-EVAL is used,
+  when Wakeup push-button is pressed, LED1 toggles
+  when Key push-button is pressed, LED2 toggles
+
+In this example, EXTI0_Config() function can be substituted by 
+STM_EVAL_PBInit(Button_WAKEUP, Mode_EXTI) and EXTI9_5_Config() by 
+STM_EVAL_PBInit(Button_KEY, Mode_EXTI) provided in the STM3210XX-EVAL driver.

+@par Hardware and Software environment 
+
+  - This example runs on STM32F10x Connectivity line, High-Density, High-Density
+    Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density 
+    and Low-Density Value line Devices.
+  
+  - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
+    Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL 
+    (Connectivity line), STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL 
+    (Medium-Density) evaluation boards and can be easily tailored to any other 
+    supported device and development board.
+    To select the STMicroelectronics evaluation board used to run the example, 
+    uncomment the corresponding line in stm32_eval.h file (under Utilities\STM32_EVAL)
+
+  - STM32100E-EVAL Set-up 
+    - Use LED1 and LED2 connected to PF.06 and PF.07 pin
+    - Use the Key push-button connected to pin PG.08 (EXTI Line8). 
+    - Use the Wakeup push-button connected to pin PA.00 (EXTI Line0).
+    @note  the jumper JP4 must be not fit to be able to use the Wakeup push-button
+        
+  - STM32100B-EVAL Set-up 
+    - Use LED1 and LED2 connected to PC.06 and PC.07 pin
+    - Use the Key push-button connected to pin PB.09 (EXTI Line9). 
+    - Use the Wakeup push-button connected to pin PA.00 (EXTI Line0).
+        
+  - STM3210C-EVAL Set-up 
+    - Use LED1 and LED2 connected to PD.07 and PD.13 pin
+    - Use the Key push-button connected to pin PB.09 (EXTI Line9).
+    - Use the Wakeup push-button connected to pin PA.00 (EXTI Line0). Make sure 
+      that the Jumper 14 is in position 2<->3.
+      
+  - STM3210E-EVAL Set-up 
+    - Use LED1 and LED2 connected to PF.06 and PF.07 pin
+    - Use the Key push-button connected to pin PG.08 (EXTI Line8). 
+    - Use the Wakeup push-button connected to pin PA.00 (EXTI Line0).
+    @note  the jumper JP4 must be not fit to be able to use the Wakeup push-button
+    
+  - STM3210B-EVAL Set-up 
+    - Use LED1 and LED2 connected to PC.06 and PC.07 pin
+    - Use the Key push-button connected to pin PB.09 (EXTI Line9).     
+    - Use the Wakeup push-button connected to pin PA.00 (EXTI Line0).
