+  * @brief   PCCARD HAL module driver.
+  *          This file provides a generic firmware to drive PCCARD memories mounted 
+  *          as external device.

+ ===============================================================================
+                        ##### How to use this driver #####
+ ===============================================================================  
+   [..]
+     This driver is a generic layered driver which contains a set of APIs used to 
+     control PCCARD/compact flash memories. It uses the FMC/FSMC layer functions 
+     to interface with PCCARD devices. This driver is used for:
+    
+    (+) PCCARD/compact flash memory configuration sequence using the function 
+        HAL_PCCARD_Init() with control and timing parameters for both common and 
+        attribute spaces.
+            
+    (+) Read PCCARD/compact flash memory maker and device IDs using the function
+        HAL_CF_Read_ID(). The read information is stored in the CompactFlash_ID 
+        structure declared by the function caller. 
+        
+    (+) Access PCCARD/compact flash memory by read/write operations using the functions
+        HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector. 
+        
+    (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_CF_Reset().
+        
+    (+) Perform PCCARD/compact flash erase sector operation using the function 
+        HAL_CF_Erase_Sector().
+    
+    (+) Read the PCCARD/compact flash status operation using the function HAL_CF_ReadStatus().
+     
+    (+) You can monitor the PCCARD/compact flash  device HAL state by calling the function
+        HAL_PCCARD_GetState()     
+        
+   [..]
+     (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash 
+         operations. If a PCCARD/compact flash device contains different operations 
+         and/or implementations, it should be implemented separately.
