===============================================================================
##### 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.
