| * @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 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_PCCARD_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(), to read/write sector. |
| |
| (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_PCCARD_Reset(). |
| |
| (+) Perform PCCARD/compact flash erase sector operation using the function |
| HAL_PCCARD_Erase_Sector(). |
| |
| (+) Read the PCCARD/compact flash status operation using the function HAL_PCCARD_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. |
