                        ##### How to use this driver #####
 ===============================================================================
  [..]
    *** Initialization ***
    ======================
    [..]
      (#) As prerequisite, fill in the HAL_OSPI_MspInit() :
        (++) Enable OctoSPI and OctoSPIM clocks interface with __HAL_RCC_OSPIx_CLK_ENABLE().
        (++) Reset OctoSPI IP with __HAL_RCC_OSPIx_FORCE_RESET() and __HAL_RCC_OSPIx_RELEASE_RESET().
        (++) Enable the clocks for the OctoSPI GPIOS with __HAL_RCC_GPIOx_CLK_ENABLE().
        (++) Configure these OctoSPI pins in alternate mode using HAL_GPIO_Init().
        (++) If interrupt or DMA mode is used, enable and configure OctoSPI global
            interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
        (++) If DMA mode is used, enable the clocks for the OctoSPI DMA channel 
            with __HAL_RCC_DMAx_CLK_ENABLE(), configure DMA with HAL_DMA_Init(), 
            link it with OctoSPI handle using __HAL_LINKDMA(), enable and configure 
            DMA channel global interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
      (#) Configure the fifo threshold, the dual-quad mode, the memory type, the 
          device size, the CS high time, the free running clock, the clock mode, 
          the wrap size, the clock prescaler, the sample shifting, the hold delay 
          and the CS boundary using the HAL_OSPI_Init() function.
      (#) When using Hyperbus, configure the RW recovery time, the access time, 
          the write latency and the latency mode unsing the HAL_OSPI_HyperbusCfg() 
          function.

    *** Indirect functional mode ***
    ================================
    [..]
      (#) In regular mode, configure the command sequence using the HAL_OSPI_Command() 
          or HAL_OSPI_Command_IT() functions :
         (++) Instruction phase : the mode used and if present the size, the instruction 
              opcode and the DTR mode.
         (++) Address phase : the mode used and if present the size, the address 
              value and the DTR mode.
         (++) Alternate-bytes phase : the mode used and if present the size, the 
              alternate bytes values and the DTR mode.
         (++) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase).
         (++) Data phase : the mode used and if present the number of bytes and the DTR mode.
         (++) Data strobe (DQS) mode : the activation (or not) of this mode
         (++) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
         (++) Flash identifier : in dual-quad mode, indicates which flash is concerned
         (++) Operation type : always common configuration
      (#) In Hyperbus mode, configure the command sequence using the HAL_OSPI_HyperbusCmd() 
          function :
         (++) Address space : indicate if the access will be done in register or memory 
         (++) Address size
         (++) Number of data
         (++) Data strobe (DQS) mode : the activation (or not) of this mode
      (#) If no data is required for the command (only for regular mode, not for 
          Hyperbus mode), it is sent directly to the memory :
         (++) In polling mode, the output of the function is done when the transfer is complete.
         (++) In interrupt mode, HAL_OSPI_CmdCpltCallback() will be called when the transfer is complete.
      (#) For the indirect write mode, use HAL_OSPI_Transmit(), HAL_OSPI_Transmit_DMA() or 
          HAL_OSPI_Transmit_IT() after the command configuration :
         (++) In polling mode, the output of the function is done when the transfer is complete.
         (++) In interrupt mode, HAL_OSPI_FifoThresholdCallback() will be called when the fifo threshold 
             is reached and HAL_OSPI_TxCpltCallback() will be called when the transfer is complete.
         (++) In DMA mode, HAL_OSPI_TxHalfCpltCallback() will be called at the half transfer and 
             HAL_OSPI_TxCpltCallback() will be called when the transfer is complete.
      (#) For the indirect read mode, use HAL_OSPI_Receive(), HAL_OSPI_Receive_DMA() or 
          HAL_OSPI_Receive_IT() after the command configuration :
         (++) In polling mode, the output of the function is done when the transfer is complete.
         (++) In interrupt mode, HAL_OSPI_FifoThresholdCallback() will be called when the fifo threshold 
             is reached and HAL_OSPI_RxCpltCallback() will be called when the transfer is complete.
         (++) In DMA mode, HAL_OSPI_RxHalfCpltCallback() will be called at the half transfer and 
             HAL_OSPI_RxCpltCallback() will be called when the transfer is complete.

    *** Auto-polling functional mode ***
    ====================================
    [..]
      (#) Configure the command sequence by the same way than the indirect mode
      (#) Configure the auto-polling functional mode using the HAL_OSPI_AutoPolling() 
          or HAL_OSPI_AutoPolling_IT() functions :
         (++) The size of the status bytes, the match value, the mask used, the match mode (OR/AND),
             the polling interval and the automatic stop activation.
      (#) After the configuration :
         (++) In polling mode, the output of the function is done when the status match is reached. The
             automatic stop is activated to avoid an infinite loop.
         (++) In interrupt mode, HAL_OSPI_StatusMatchCallback() will be called each time the status match is reached.

    *** Memory-mapped functional mode ***
    =====================================
    [..]
      (#) Configure the command sequence by the same way than the indirect mode except 
          for the operation type in regular mode :
         (++) Operation type equals to read configuration : the command configuration 
              applies to read access in memory-mapped mode
         (++) Operation type equals to write configuration : the command configuration 
              applies to write access in memory-mapped mode
         (++) Both read and write configuration should be performed before activating 
              memory-mapped mode
      (#) Configure the memory-mapped functional mode using the HAL_OSPI_MemoryMapped() 
          functions :
         (++) The timeout activation and the timeout period.
      (#) After the configuration, the OctoSPI will be used as soon as an access on the AHB is done on 
          the address range. HAL_OSPI_TimeOutCallback() will be called when the timeout expires.

    *** Errors management and abort functionality ***
    =================================================
    [..]
      (#) HAL_OSPI_GetError() function gives the error raised during the last operation.
      (#) HAL_OSPI_Abort() and HAL_OSPI_AbortIT() functions aborts any on-going operation and 
          flushes the fifo :
         (++) In polling mode, the output of the function is done when the transfer 
              complete bit is set and the busy bit cleared.
         (++) In interrupt mode, HAL_OSPI_AbortCpltCallback() will be called when 
              the transfer complete bit is set.

    *** Control functions ***
    =========================
    [..]
      (#) HAL_OSPI_GetState() function gives the current state of the HAL OctoSPI driver.
      (#) HAL_OSPI_SetTimeout() function configures the timeout value used in the driver.
      (#) HAL_OSPI_SetFifoThreshold() function configures the threshold on the Fifo of the OSPI IP.
      (#) HAL_OSPI_GetFifoThreshold() function gives the current of the Fifo's threshold 

    *** IO manager configuration functions ***
    ==========================================
    [..]
      (#) HAL_OSPIM_Config() function configures the IO manager for the OctoSPI instance.
