===============================================================================
##### 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 raised during the last operation.
(#) HAL_QSPI_Abort() and HAL_QSPI_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_QSPI_AbortCpltCallback() will be called when
the transfer complete bi is set.
*** Control functions ***
=========================
[..]
(#) HAL_QSPI_GetState() function gives the current state of the HAL QuadSPI driver.
(#) HAL_QSPI_SetTimeout() function configures the timeout value used in the driver.
(#) HAL_QSPI_SetFifoThreshold() function configures the threshold on the Fifo of the QSPI IP.
(#) HAL_QSPI_GetFifoThreshold() function gives the current of the Fifo's threshold
*** Workarounds linked to Silicon Limitation ***
====================================================
[..]
(#) Workarounds Implemented inside HAL Driver
(++) Extra data written in the FIFO at the end of a read transfer
