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 + * + *
