<> 144:ef7eb2e8f9f7 15 [..]
<> 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 FMC 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() with control and timing parameters for both common and
<> 144:ef7eb2e8f9f7 22 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(). The read information is stored in the CompactFlash_ID
<> 144:ef7eb2e8f9f7 26 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(), to read/write sector.
<> 144:ef7eb2e8f9f7 30
<> 144:ef7eb2e8f9f7 31 (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_PCCARD_Reset().
<> 144:ef7eb2e8f9f7 32
<> 144:ef7eb2e8f9f7 33 (+) Perform PCCARD/compact flash erase sector operation using the function
<> 144:ef7eb2e8f9f7 34 HAL_PCCARD_Erase_Sector().
<> 144:ef7eb2e8f9f7 35
<> 144:ef7eb2e8f9f7 36 (+) Read the PCCARD/compact flash status operation using the function HAL_PCCARD_ReadStatus().
<> 144:ef7eb2e8f9f7 37
<> 144:ef7eb2e8f9f7 38 (+) You can monitor the PCCARD/compact flash device HAL state by calling the function
<> 144:ef7eb2e8f9f7 39 HAL_PCCARD_GetState()
<> 144:ef7eb2e8f9f7 40
<> 144:ef7eb2e8f9f7 41 [..]
<> 144:ef7eb2e8f9f7 42 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
<> 144:ef7eb2e8f9f7 43 operations. If a PCCARD/compact flash device contains different operations
<> 144:ef7eb2e8f9f7 44 and/or implementations, it should be implemented separately.
