 ===============================================================================
                        ##### How to use this driver #####
 ===============================================================================
  [..]
    *** Initialization ***
    ======================
    [..]
      (#) As prerequisite, fill in the HAL_QSPI_MspInit() :
        (+) Enable QuadSPI clock interface with __HAL_RCC_QSPI_CLK_ENABLE().
        (+) Reset QuadSPI IP with __HAL_RCC_QSPI_FORCE_RESET() and __HAL_RCC_QSPI_RELEASE_RESET().
        (+) Enable the clocks for the QuadSPI GPIOS with __HAL_RCC_GPIOx_CLK_ENABLE().
        (+) Configure these QuadSPI pins in alternate mode using HAL_GPIO_Init().
        (+) If interrupt mode is used, enable and configure QuadSPI global
            interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
        (+) If DMA mode is used, enable the clocks for the QuadSPI DMA channel 
            with __HAL_RCC_DMAx_CLK_ENABLE(), configure DMA with HAL_DMA_Init(), 
            link it with QuadSPI handle using __HAL_LINKDMA(), enable and configure 
            DMA channel global interrupt with HAL_NVIC_SetPriority() and HAL_NVIC_EnableIRQ().
      (#) Configure the flash size, the clock prescaler, the fifo threshold, the
          clock mode, the sample shifting and the CS high time using the HAL_QSPI_Init() function.

    *** Indirect functional mode ***
    ================================
    [..]
      (#) Configure the command sequence using the HAL_QSPI_Command() or HAL_QSPI_Command_IT() 
          functions :
         (+) Instruction phase : the mode used and if present the instruction opcode.
         (+) Address phase : the mode used and if present the size and the address value.
         (+) Alternate-bytes phase : the mode used and if present the size and the alternate 
             bytes values.
         (+) 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.
         (+) Double Data Rate (DDR) mode : the activation (or not) of this mode and the delay 
             if activated.
         (+) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
      (#) If no data is required for the command, 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_QSPI_CmdCpltCallback() will be called when the transfer is complete.
      (#) For the indirect write mode, use HAL_QSPI_Transmit(), HAL_QSPI_Transmit_DMA() or 
          HAL_QSPI_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_QSPI_FifoThresholdCallback() will be called when the fifo threshold 
             is reached and HAL_QSPI_TxCpltCallback() will be called when the transfer is complete.
         (+) In DMA mode, HAL_QSPI_TxHalfCpltCallback() will be called at the half transfer and 
             HAL_QSPI_TxCpltCallback() will be called when the transfer is complete.
      (#) For the indirect read mode, use HAL_QSPI_Receive(), HAL_QSPI_Receive_DMA() or 
          HAL_QSPI_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_QSPI_FifoThresholdCallback() will be called when the fifo threshold 
             is reached and HAL_QSPI_RxCpltCallback() will be called when the transfer is complete.
         (+) In DMA mode, HAL_QSPI_RxHalfCpltCallback() will be called at the half transfer and 
             HAL_QSPI_RxCpltCallback() will be called when the transfer is complete.

    *** Auto-polling functional mode ***
    ====================================
    [..]
      (#) Configure the command sequence and the auto-polling functional mode using the 
          HAL_QSPI_AutoPolling() or HAL_QSPI_AutoPolling_IT() functions :
         (+) Instruction phase : the mode used and if present the instruction opcode.
         (+) Address phase : the mode used and if present the size and the address value.
         (+) Alternate-bytes phase : the mode used and if present the size and the alternate 
             bytes values.
         (+) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase).
         (+) Data phase : the mode used.
         (+) Double Data Rate (DDR) mode : the activation (or not) of this mode and the delay 
             if activated.
         (+) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
         (+) 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_QSPI_StatusMatchCallback() will be called each time the status match is reached.

    *** Memory-mapped functional mode ***
    =====================================
    [..]
      (#) Configure the command sequence and the memory-mapped functional mode using the 
          HAL_QSPI_MemoryMapped() functions :
         (+) Instruction phase : the mode used and if present the instruction opcode.
         (+) Address phase : the mode used and the size.
         (+) Alternate-bytes phase : the mode used and if present the size and the alternate 
             bytes values.
         (+) Dummy-cycles phase : the number of dummy cycles (mode used is same as data phase).
         (+) Data phase : the mode used.
         (+) Double Data Rate (DDR) mode : the activation (or not) of this mode and the delay 
             if activated.
         (+) Sending Instruction Only Once (SIOO) mode : the activation (or not) of this mode.
         (+) The timeout activation and the timeout period.
      (#) After the configuration, the QuadSPI will be used as soon as an access on the AHB is done on 
          the address range. HAL_QSPI_TimeOutCallback() will be called when the timeout expires.

    *** Errors management and abort functionality ***
    ==================================================
    [..]
      (#) HAL_QSPI_GetError() function gives the error rised during the last operation.
      (#) HAL_QSPI_Abort() function aborts any on-going operation and flushes the fifo.
      (#) HAL_QSPI_GetState() function gives the current state of the HAL QuadSPI driver.

    *** Workarounds linked to Silicon Limitation ***
    ====================================================
    [..]
      (#) Workarounds Implemented inside HAL Driver
         (+) Extra data written in the FIFO at the end of a read transfer
