+ @verbatim
+ ==============================================================================
+ ##### How to use this driver #####
+ ==============================================================================
+ [..]
+ The PSSI HAL driver can be used as follows:
+
+ (#) Declare a PSSI_HandleTypeDef handle structure, for example:
+ PSSI_HandleTypeDef hpssi;
+
+ (#) Initialize the PSSI low level resources by implementing the @ref HAL_PSSI_MspInit() API:
+ (##) Enable the PSSIx interface clock
+ (##) PSSI pins configuration
+ (+++) Enable the clock for the PSSI GPIOs
+ (+++) Configure PSSI pins as alternate function open-drain
+ (##) NVIC configuration if you need to use interrupt process
+ (+++) Configure the PSSIx interrupt priority
+ (+++) Enable the NVIC PSSI IRQ Channel
+ (##) DMA Configuration if you need to use DMA process
+ (+++) Declare DMA_HandleTypeDef handles structure for the transmit and receive
+ (+++) Enable the DMAx interface clock
+ (+++) Configure the DMA handle parameters
+ (+++) Configure the DMA Tx and Rx
+ (+++) Associate the initialized DMA handle to the hpssi DMA Tx and Rx handle
+ (+++) Configure the priority and enable the NVIC for the transfer complete interrupt on
+ the DMA Tx and Rx
+
+ (#) Configure the Communication Bus Width, Control Signals, Input Polarity and Output Polarity
+ in the hpssi Init structure.
+
+ (#) Initialize the PSSI registers by calling the @ref HAL_PSSI_Init(), configure also the low level Hardware
+ (GPIO, CLOCK, NVIC...etc) by calling the customized @ref HAL_PSSI_MspInit(&hpssi) API.
+
+
+ (#) For PSSI IO operations, two operation modes are available within this driver :
+
+ *** Polling mode IO operation ***
+ =================================
+ [..]
+ (+) Transmit an amount of data by byte in blocking mode using @ref HAL_PSSI_Transmit()
+ (+) Receive an amount of data by byte in blocking mode using @ref HAL_PSSI_Receive()
+
+ *** DMA mode IO operation ***
+ ==============================
+ [..]
+ (+) Transmit an amount of data in non-blocking mode (DMA) using
+ @ref HAL_PSSI_Transmit_DMA()
+ (+) At transmission end of transfer, @ref HAL_PSSI_TxCpltCallback() is executed and user can
+ add his own code by customization of function pointer @ref HAL_PSSI_TxCpltCallback()
+ (+) Receive an amount of data in non-blocking mode (DMA) using
+ @ref HAL_PSSI_Receive_DMA()
+ (+) At reception end of transfer, @ref HAL_PSSI_RxCpltCallback() is executed and user can
+ add his own code by customization of function pointer @ref HAL_PSSI_RxCpltCallback()
+ (+) In case of transfer Error, @ref HAL_PSSI_ErrorCallback() function is executed and user can
+ add his own code by customization of function pointer @ref HAL_PSSI_ErrorCallback()
+ (+) Abort a PSSI process communication with Interrupt using @ref HAL_PSSI_Abort_IT()
+ (+) End of abort process, @ref HAL_PSSI_AbortCpltCallback() is executed and user can
+ add his own code by customization of function pointer @ref HAL_PSSI_AbortCpltCallback()
+
+ *** PSSI HAL driver macros list ***
+ ==================================
+ [..]
+ Below the list of most used macros in PSSI HAL driver.
+
+ (+) @ref HAL_PSSI_ENABLE : Enable the PSSI peripheral
+ (+) @ref HAL_PSSI_DISABLE : Disable the PSSI peripheral
+ (+) @ref HAL_PSSI_GET_FLAG : Check whether the specified PSSI flag is set or not
+ (+) @ref HAL_PSSI_CLEAR_FLAG : Clear the specified PSSI pending flag
+ (+) @ref HAL_PSSI_ENABLE_IT : Enable the specified PSSI interrupt
+ (+) @ref HAL_PSSI_DISABLE_IT : Disable the specified PSSI interrupt
+
+ *** Callback registration ***
+ =============================================
+ Use Functions @ref HAL_PSSI_RegisterCallback() or @ref HAL_PSSI_RegisterAddrCallback()
+ to register an interrupt callback.
+
+ Function @ref HAL_PSSI_RegisterCallback() allows to register following callbacks:
+ (+) TxCpltCallback : callback for transmission end of transfer.
+ (+) RxCpltCallback : callback for reception end of transfer.
+ (+) ErrorCallback : callback for error detection.
+ (+) AbortCpltCallback : callback for abort completion process.
+ (+) MspInitCallback : callback for Msp Init.
+ (+) MspDeInitCallback : callback for Msp DeInit.
+ This function takes as parameters the HAL peripheral handle, the Callback ID
+ and a pointer to the user callback function.
+
+
+ Use function @ref HAL_PSSI_UnRegisterCallback to reset a callback to the default
+ weak function.
+ @ref HAL_PSSI_UnRegisterCallback takes as parameters the HAL peripheral handle,
+ and the Callback ID.
+ This function allows to reset following callbacks:
+ (+) TxCpltCallback : callback for transmission end of transfer.
+ (+) RxCpltCallback : callback for reception end of transfer.
+ (+) ErrorCallback : callback for error detection.
+ (+) AbortCpltCallback : callback for abort completion process.
+ (+) MspInitCallback : callback for Msp Init.
+ (+) MspDeInitCallback : callback for Msp DeInit.
+
+
+ By default, after the @ref HAL_PSSI_Init() and when the state is @ref HAL_PSSI_STATE_RESET
+ all callbacks are set to the corresponding weak functions:
+ examples @ref HAL_PSSI_TxCpltCallback(), @ref HAL_PSSI_RxCpltCallback().
+ Exception done for MspInit and MspDeInit functions that are
+ reset to the legacy weak functions in the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit() only when
+ these callbacks are null (not registered beforehand).
+ If MspInit or MspDeInit are not null, the @ref HAL_PSSI_Init()/ @ref HAL_PSSI_DeInit()
+ keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
+
+ Callbacks can be registered/unregistered in @ref HAL_PSSI_STATE_READY state only.
+ Exception done MspInit/MspDeInit functions that can be registered/unregistered
+ in @ref HAL_PSSI_STATE_READY or @ref HAL_PSSI_STATE_RESET state,
+ thus registered (user) MspInit/DeInit callbacks can be used during the Init/DeInit.
+ Then, the user first registers the MspInit/MspDeInit user callbacks
+ using @ref HAL_PSSI_RegisterCallback() before calling @ref HAL_PSSI_DeInit()
+ or @ref HAL_PSSI_Init() function.
+
+
+ [..]
