<> 144:ef7eb2e8f9f7 16 This driver is a generic layered driver which contains a set of APIs used to
<> 144:ef7eb2e8f9f7 17 control PCCARD/compact flash memories. It uses the FSMC layer functions
<> 144:ef7eb2e8f9f7 18 to interface with PCCARD devices. This driver is used for:
<> 144:ef7eb2e8f9f7 19
<> 144:ef7eb2e8f9f7 20 (+) PCCARD/Compact Flash memory configuration sequence using the function
<> 144:ef7eb2e8f9f7 21 HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for
<> 144:ef7eb2e8f9f7 22 both common and attribute spaces.
<> 144:ef7eb2e8f9f7 23
<> 144:ef7eb2e8f9f7 24 (+) Read PCCARD/Compact Flash memory maker and device IDs using the function
<> 144:ef7eb2e8f9f7 25 HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in
<> 144:ef7eb2e8f9f7 26 the CompactFlash_ID structure declared by the function caller.
<> 144:ef7eb2e8f9f7 27
<> 144:ef7eb2e8f9f7 28 (+) Access PCCARD/Compact Flash memory by read/write operations using the functions
<> 144:ef7eb2e8f9f7 29 HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() -
<> 144:ef7eb2e8f9f7 30 HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
<> 144:ef7eb2e8f9f7 31
<> 144:ef7eb2e8f9f7 32 (+) Perform PCCARD/Compact Flash Reset chip operation using the function
<> 144:ef7eb2e8f9f7 33 HAL_PCCARD_Reset()/HAL_CF_Reset.
<> 144:ef7eb2e8f9f7 34
<> 144:ef7eb2e8f9f7 35 (+) Perform PCCARD/Compact Flash erase sector operation using the function
<> 144:ef7eb2e8f9f7 36 HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.
<> 144:ef7eb2e8f9f7 37
<> 144:ef7eb2e8f9f7 38 (+) Read the PCCARD/Compact Flash status operation using the function
<> 144:ef7eb2e8f9f7 39 HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().
<> 144:ef7eb2e8f9f7 40
<> 144:ef7eb2e8f9f7 41 (+) You can monitor the PCCARD/Compact Flash device HAL state by calling
<> 144:ef7eb2e8f9f7 42 the function HAL_PCCARD_GetState()/HAL_CF_GetState()
<> 144:ef7eb2e8f9f7 43
<> 144:ef7eb2e8f9f7 44 [..]
<> 144:ef7eb2e8f9f7 45 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
<> 144:ef7eb2e8f9f7 46 operations. If a PCCARD/Compact Flash device contains different operations
<> 144:ef7eb2e8f9f7 47 and/or implementations, it should be implemented separately.
