Functions
void	avrf_mem_init (void)
	This function initializes the hw/sw ressources required to drive the AVR Flash.
Ctrl_status	avrf_test_unit_ready (void)
	This function tests the state of the AVR Flash.
Ctrl_status	avrf_read_capacity (U32 *u32_nb_sector)
	This function gives the address of the last valid sector.
Bool	avrf_wr_protect (void)
	This function returns the write protected status of the memory.
Bool	avrf_removal (void)
	This function tells if the memory has been removed or not.
Ctrl_status	avrf_read_10 (U32 addr, U16 nb_sector)
	This function performs a read operation of n sectors from a given address on.
Ctrl_status	avrf_write_10 (U32 addr, U16 nb_sector)
	This fonction initialise the memory for a write operation.
bit	avrf_read_open (Uint32 pos)
	This function opens a DF memory in read mode at a given sector address.
void	avrf_read_close (void)
	This function unselects the current DF memory.
bit	avrf_read_sector (Uint16 nb_sector)
	This function is optimized and writes nb-sector * 512 Bytes from DataFlash memory to USB controller.
bit	avrf_write_open (Uint32 pos)
	This function opens a DF memory in write mode at a given sector address.
void	avrf_write_close (void)
	This function fills the end of the logical sector (512B) and launch page programming.
bit	avrf_write_sector (Uint16 nb_sector)
	This function is optimized and writes nb-sector * 512 Bytes from USB controller to DataFlash memory.
Ctrl_status	avrf_usb_read ()
	This fonction transfer the memory data (programed in scsi_read_10) directly to the usb interface.
Ctrl_status	avrf_usb_write (void)
	This fonction transfer the usb data (programed in scsi_write_10) directly to the memory data.
