  * @brief   PCCARD HAL module driver.+

−

                        ##### 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()/HAL_CF_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_PCCARD_Read_ID()/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_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() - +
−
        HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector. +
−
        +
−
    (+) Perform PCCARD/Compact Flash Reset chip operation using the function+
−
        HAL_PCCARD_Reset()/HAL_CF_Reset.+
−
        +
−
    (+) Perform PCCARD/Compact Flash erase sector operation using the function +
−
        HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.+
−
    +
−
    (+) Read the PCCARD/Compact Flash status operation using the function+
−
        HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().+
−
     +
−
    (+) You can monitor the PCCARD/Compact Flash  device HAL state by calling+
−
        the function HAL_PCCARD_GetState()/HAL_CF_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.+
