- * @version V1.1.0
- * @date 19-June-2014
- * @brief PCCARD HAL module driver.
- * This file provides a generic firmware to drive PCCARD memories mounted
- * as external device.
- *
- @verbatim
- ===============================================================================
- ##### 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() with control and timing parameters for both common and
- attribute spaces.
-
- (+) Read PCCARD/compact flash memory maker and device IDs using the function
- 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_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
-
- (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_CF_Reset().
-
- (+) Perform PCCARD/compact flash erase sector operation using the function
- HAL_CF_Erase_Sector().
-
- (+) Read the PCCARD/compact flash status operation using the function HAL_CF_ReadStatus().
-
- (+) You can monitor the PCCARD/compact flash device HAL state by calling the function
- HAL_PCCARD_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.
