##### How to use this driver #####
==============================================================================
[..]
The PKA HAL driver can be used as follows:
(#) Declare a PKA_HandleTypeDef handle structure, for example: PKA_HandleTypeDef hpka;
(#) Initialize the PKA low level resources by implementing the HAL_PKA_MspInit() API:
(##) Enable the PKA interface clock
(##) NVIC configuration if you need to use interrupt process
(+++) Configure the PKA interrupt priority
(+++) Enable the NVIC PKA IRQ Channel
(#) Initialize the PKA registers by calling the HAL_PKA_Init() API which trig
HAL_PKA_MspInit().
(#) Fill entirely the input structure corresponding to your operation:
For instance: PKA_ModExpInTypeDef for HAL_PKA_ModExp().
(#) Execute the operation (in polling or interrupt) and check the returned value.
(#) Retrieve the result of the operation (For instance, HAL_PKA_ModExp_GetResult for
HAL_PKA_ModExp operation). The function to gather the result is different for each
kind of operation. The correspondence can be found in the following section.
(#) Call the function HAL_PKA_DeInit() to restore the default configuration which trig
HAL_PKA_MspDeInit().

*** Montgomery parameter ***
=================================
(+) For some operation, the computation of the Montgomery parameter is a prerequisite.
(+) Input structure requires buffers as uint8_t array.
(+) Output structure requires buffers as uint32_t array.(Only used inside PKA).
(+) You can compute the Montgomery parameter using:
(++) HAL_PKA_MontgomeryParam().

*** Polling mode operation ***
===================================
[..]
(+) When an operation is started in polling mode, the function returns when:
(++) A timeout is encounter.
(++) The operation is completed.
*** Interrupt mode operation ***
===================================
[..]
(+) Add HAL_PKA_IRQHandler to the IRQHandler of PKA.
(+) Enable the IRQ using HAL_NVIC_EnableIRQ().
(+) When an operation is started in interrupt mode, the function returns immediately.
(+) When the operation is completed, the callback HAL_PKA_OperationCpltCallback is called.
(+) When an error is encountered, the callback HAL_PKA_ErrorCallback is called.
(+) To stop any operation in interrupt mode, use HAL_PKA_Abort().
*** Utilities ***
===================================
[..]
(+) To clear the PKA RAM, use HAL_PKA_RAMReset().
(+) To get current state, use HAL_PKA_GetState().
(+) To get current error, use HAL_PKA_GetError().
*** Callback registration ***
=============================================
[..]
The compilation flag USE_HAL_PKA_REGISTER_CALLBACKS, when set to 1,
allows the user to configure dynamically the driver callbacks.
Use Functions HAL_PKA_RegisterCallback()
to register an interrupt callback.
[..]
Function HAL_PKA_RegisterCallback() allows to register following callbacks:
(+) OperationCpltCallback : callback for End of operation.
(+) ErrorCallback : callback for error detection.
(+) 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 HAL_PKA_UnRegisterCallback to reset a callback to the default
weak function.
[..]
HAL_PKA_UnRegisterCallback takes as parameters the HAL peripheral handle,
and the Callback ID.
This function allows to reset following callbacks:
(+) OperationCpltCallback : callback for End of operation.
(+) ErrorCallback : callback for error detection.
(+) MspInitCallback : callback for Msp Init.
(+) MspDeInitCallback : callback for Msp DeInit.
[..]
By default, after the HAL_PKA_Init() and when the state is HAL_PKA_STATE_RESET
all callbacks are set to the corresponding weak functions:
examples HAL_PKA_OperationCpltCallback(), HAL_PKA_ErrorCallback().
Exception done for MspInit and MspDeInit functions that are
reset to the legacy weak functions in the HAL_PKA_Init()/ HAL_PKA_DeInit() only when
these callbacks are null (not registered beforehand).
[..]
If MspInit or MspDeInit are not null, the HAL_PKA_Init()/ HAL_PKA_DeInit()
keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.
[..]
Callbacks can be registered/unregistered in HAL_PKA_STATE_READY state only.
Exception done MspInit/MspDeInit functions that can be registered/unregistered
in HAL_PKA_STATE_READY or HAL_PKA_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 HAL_PKA_RegisterCallback() before calling HAL_PKA_DeInit()
or HAL_PKA_Init() function.
[..]
When the compilation flag USE_HAL_PKA_REGISTER_CALLBACKS is set to 0 or
not defined, the callback registration feature is not available and all callbacks
are set to the corresponding weak functions.
