mbed_official 87:085cde657901 13 ##### How to use this driver #####
mbed_official 87:085cde657901 14 ===============================================================================
mbed_official 87:085cde657901 15 [..]
mbed_official 87:085cde657901 16 This driver is a generic layered driver which contains a set of APIs used to
mbed_official 87:085cde657901 17 control PCCARD/compact flash memories. It uses the FMC/FSMC layer functions
mbed_official 87:085cde657901 18 to interface with PCCARD devices. This driver is used for:
mbed_official 87:085cde657901 19
mbed_official 87:085cde657901 20 (+) PCCARD/compact flash memory configuration sequence using the function
mbed_official 87:085cde657901 21 HAL_PCCARD_Init() with control and timing parameters for both common and
mbed_official 87:085cde657901 22 attribute spaces.
mbed_official 87:085cde657901 23
mbed_official 87:085cde657901 24 (+) Read PCCARD/compact flash memory maker and device IDs using the function
mbed_official 87:085cde657901 25 HAL_CF_Read_ID(). The read information is stored in the CompactFlash_ID
mbed_official 87:085cde657901 26 structure declared by the function caller.
mbed_official 87:085cde657901 27
mbed_official 87:085cde657901 28 (+) Access PCCARD/compact flash memory by read/write operations using the functions
mbed_official 87:085cde657901 29 HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
mbed_official 87:085cde657901 30
mbed_official 87:085cde657901 31 (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_CF_Reset().
mbed_official 87:085cde657901 32
mbed_official 87:085cde657901 33 (+) Perform PCCARD/compact flash erase sector operation using the function
mbed_official 87:085cde657901 34 HAL_CF_Erase_Sector().
mbed_official 87:085cde657901 35
mbed_official 87:085cde657901 36 (+) Read the PCCARD/compact flash status operation using the function HAL_CF_ReadStatus().
mbed_official 87:085cde657901 37
mbed_official 87:085cde657901 38 (+) You can monitor the PCCARD/compact flash device HAL state by calling the function
mbed_official 87:085cde657901 39 HAL_PCCARD_GetState()
mbed_official 87:085cde657901 40
mbed_official 87:085cde657901 41 [..]
mbed_official 87:085cde657901 42 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
mbed_official 87:085cde657901 43 operations. If a PCCARD/compact flash device contains different operations
mbed_official 87:085cde657901 44 and/or implementations, it should be implemented separately.
