lypinator 0:bb348c97df44 5 * @brief PCCARD HAL module driver.
lypinator 0:bb348c97df44 6 * This file provides a generic firmware to drive PCCARD memories mounted

lypinator 0:bb348c97df44 11 ##### How to use this driver #####
lypinator 0:bb348c97df44 12 ===============================================================================
lypinator 0:bb348c97df44 13 [..]
lypinator 0:bb348c97df44 14 This driver is a generic layered driver which contains a set of APIs used to
lypinator 0:bb348c97df44 15 control PCCARD/compact flash memories. It uses the FMC/FSMC layer functions
lypinator 0:bb348c97df44 16 to interface with PCCARD devices. This driver is used for:
lypinator 0:bb348c97df44 17
lypinator 0:bb348c97df44 18 (+) PCCARD/Compact Flash memory configuration sequence using the function
lypinator 0:bb348c97df44 19 HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for
lypinator 0:bb348c97df44 20 both common and attribute spaces.
lypinator 0:bb348c97df44 21
lypinator 0:bb348c97df44 22 (+) Read PCCARD/Compact Flash memory maker and device IDs using the function
lypinator 0:bb348c97df44 23 HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in
lypinator 0:bb348c97df44 24 the CompactFlash_ID structure declared by the function caller.
lypinator 0:bb348c97df44 25
lypinator 0:bb348c97df44 26 (+) Access PCCARD/Compact Flash memory by read/write operations using the functions
lypinator 0:bb348c97df44 27 HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() -
lypinator 0:bb348c97df44 28 HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
lypinator 0:bb348c97df44 29
lypinator 0:bb348c97df44 30 (+) Perform PCCARD/Compact Flash Reset chip operation using the function
lypinator 0:bb348c97df44 31 HAL_PCCARD_Reset()/HAL_CF_Reset.
lypinator 0:bb348c97df44 32
lypinator 0:bb348c97df44 33 (+) Perform PCCARD/Compact Flash erase sector operation using the function
lypinator 0:bb348c97df44 34 HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.
lypinator 0:bb348c97df44 35
lypinator 0:bb348c97df44 36 (+) Read the PCCARD/Compact Flash status operation using the function
lypinator 0:bb348c97df44 37 HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().
lypinator 0:bb348c97df44 38
lypinator 0:bb348c97df44 39 (+) You can monitor the PCCARD/Compact Flash device HAL state by calling
lypinator 0:bb348c97df44 40 the function HAL_PCCARD_GetState()/HAL_CF_GetState()
lypinator 0:bb348c97df44 41
lypinator 0:bb348c97df44 42 [..]
lypinator 0:bb348c97df44 43 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
lypinator 0:bb348c97df44 44 operations. If a PCCARD/Compact Flash device contains different operations
lypinator 0:bb348c97df44 45 and/or implementations, it should be implemented separately.
