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()/HAL_CF_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()/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_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() - - HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector. - - (+) Perform PCCARD/Compact Flash Reset chip operation using the function - HAL_PCCARD_Reset()/HAL_CF_Reset. - - (+) Perform PCCARD/Compact Flash erase sector operation using the function - HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector. - - (+) Read the PCCARD/Compact Flash status operation using the function - HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus(). - - (+) You can monitor the PCCARD/Compact Flash device HAL state by calling - the function HAL_PCCARD_GetState()/HAL_CF_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. - - @endverbatim - ****************************************************************************** - * @attention - * - * <h2><center>© COPYRIGHT(c) 2015 STMicroelectronics</center></h2> - * - * Redistribution and use in source and binary forms, with or without modification, - * are permitted provided that the following conditions are met: - * 1.
