* @brief PSSI HAL module driver.
* This file provides firmware functions to manage the following
* functionalities of the Parallel Synchronous Slave Interface (PSSI) peripheral:
* + Initialization and de-initialization functions
* + IO operation functions
* + Peripheral State and Errors functions
*
@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.
[..]

##### Initialization and de-initialization functions #####
===============================================================================
[..] This subsection provides a set of functions allowing to initialize and
deinitialize the PSSIx peripheral:
(+) User must implement HAL_PSSI_MspInit() function in which he configures
all related peripherals resources (CLOCK, GPIO, DMA, IT and NVIC ).
(+) Call the function HAL_PSSI_Init() to configure the selected device with
the selected configuration:
(++) Data Width
(++) Control Signals
(++) Input Clock polarity
(++) Output Clock polarity
(+) Call the function HAL_PSSI_DeInit() to restore the default configuration
of the selected PSSIx peripheral.

This subsection provides a set of functions allowing to manage the PSSI data
transfers.
(#) There are two modes of transfer:
(++) Blocking mode : The communication is performed in the polling mode.
The status of all data processing is returned by the same function
after finishing transfer.
(++) No-Blocking mode : The communication is performed using DMA.
These functions return the status of the transfer startup.
The end of the data processing will be indicated through the
dedicated the DMA IRQ .
(#) Blocking mode functions are :
(++) HAL_PSSI_Transmit()
(++) HAL_PSSI_Receive()
(#) No-Blocking mode functions with DMA are :
(++) HAL_PSSI_Transmit_DMA()
(++) HAL_PSSI_Receive_DMA()
(#) A set of Transfer Complete Callbacks are provided in non Blocking mode:
