Detailed Description

PCCARD Controller functions. 

 ===============================================================================
                    PCCARD Controller functions
 ===============================================================================  

 The following sequence should be followed to configure the FSMC to interface with
 16-bit PC Card compatible memory connected to the PCCARD Bank:
 
   1. Enable the clock for the FSMC and associated GPIOs using the following functions:
          RCC_AHB3PeriphClockCmd(RCC_AHB3Periph_FSMC, ENABLE);
          RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);

   2. FSMC pins configuration 
       - Connect the involved FSMC pins to AF12 using the following function 
          GPIO_PinAFConfig(GPIOx, GPIO_PinSourcex, GPIO_AF_FSMC); 
       - Configure these FSMC pins in alternate function mode by calling the function
          GPIO_Init();    
       
   3. Declare a FSMC_PCCARDInitTypeDef structure, for example:
          FSMC_PCCARDInitTypeDef  FSMC_PCCARDInitStructure;
      and fill the FSMC_PCCARDInitStructure variable with the allowed values of
      the structure member.
      
   4. Initialize the PCCARD Controller by calling the function
          FSMC_PCCARDInit(&FSMC_PCCARDInitStructure); 

   5. Then enable the PCCARD Bank:
          FSMC_PCCARDCmd(ENABLE);  

   6. At this stage you can read/write from/to the memory connected to the PCCARD Bank.
