+@par Example Description 
+
+This example presents the MPU features on STM32F10x XL-density devices and it 
+can be easily ported to any other STM32 device supporting MPU.
+
+The example purpose (ACCESS_PERMISSION) is to configure a memory region as 
+privileged read only region and tries to perform read and write operation in 
+different mode.
+If the access is permitted LED1 is toggling. If the access is not permitted, 
+a memory management fault is generated and LED2 is ON.
+To generate an MPU memory fault exception due to an access right error, uncomment
+the following line "privilegedreadonlyarray[0] = 'e';" in the 
+"accesspermission.c " file.
+

+@par Hardware and Software environment
+  
+  - This example runs on STM32F10x XL-density Devices.
+
+  - This example has been tested with STMicroelectronics STM3210E-EVAL (High-Density
+    and XL-Density) evaluation board and can be easily tailored to any other 
+    supported device and development board.
+     
+@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 and setup your project configuration as follows
+ - Add the required example files
+   - accesspermission.c
+<ul>
+- For RIDE and TrueSTUDIO toolchains you have to follow these instructions
+
+    <li> RIDE 
+        - In the Application options -> script menu, set "Use Default Script File" 
+          to "No" and use "stm32f_flash_ROAarray.ld" as Script File. 
+          This linker is configured for STM32F. To use it with  other STM32 devices.
+          This linker should be updated.      
+        
+
+    <li> TrueSTUDIO 
+          - In the project properties window, select C/C++ Build->settings node then 
+           the C Linker->General node and use "stm32f10x_flash_ROArray.ld" as Script File.
+           This linker is configured for XL-density devices. To use it with
+           other STM32 devices, this linker should be updated.           
+</ul>    
+ 
+ - 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.
