 ==============================================================================
                       ##### How to use this driver #####
 ==============================================================================
 [..]
    The SUBGHZ HAL driver can be used as follows:

    (#) Declare a SUBGHZ_HandleTypeDef handle structure, for example:
        SUBGHZ_HandleTypeDef hUserSubghz;

    (#) Initialize the SUBGHZ low level resources by implementing the @ref HAL_SUBGHZ_MspInit() API:
        (##) PWR configuration
            (+++) Enable the SUBGHZSPI interface clock
            (+++) Enable wakeup signal of the Radio peripheral
        (##) NVIC configuration:
            (+++) Enable the NVIC Radio IRQ ITs for CPU1 (EXTI 44)
            (+++) Configure the Radio interrupt priority

    (#) Initialize the SUBGHZ handle and SUBGHZSPI SPI registers by calling the @ref HAL_SUBGHZ_Init(&hUserSubghz),
        configures also the low level Hardware (GPIO, CLOCK, NVIC...etc) by calling
        the customized @ref HAL_SUBGHZ_MspInit() API.

    (#) For SUBGHZ IO operations, polling operation modes is available within this driver :

    *** Polling mode IO operation      ***
    =====================================
    [..]
      (+) Set and execute a command in blocking mode using @ref HAL_SUBGHZ_ExecSetCmd()
      (+) Get a status blocking mode using @ref HAL_SUBGHZ_ExecGetCmd()
      (+) Write a Data Buffer in blocking mode using @ref HAL_SUBGHZ_WriteBuffer()
      (+) Read a Data Buffer  in blocking mode using @ref HAL_SUBGHZ_ReadBuffer()
      (+) Write Registers (more than 1 byte) in blocking mode using @ref HAL_SUBGHZ_WriteRegisters()
      (+) Read Registers (more than 1 byte) in blocking mode using @ref HAL_SUBGHZ_ReadRegisters()
      (+) Write Register (1 byte) in blocking mode using @ref HAL_SUBGHZ_WriteRegister()
      (+) Read Register (1 byte) in blocking mode using @ref HAL_SUBGHZ_ReadRegister()

    *** SUBGHZ HAL driver macros list ***
    =====================================
    [..]
      (+) @ref __HAL_SUBGHZ_RESET_HANDLE_STATE: Reset the SUBGHZ handle state

#if defined(GENERATOR_CALLBACK_REGISTERING_PRESENT)
     *** SUBGHZ Callback registration  ***
     =====================================

    [..]
     The compilation flag USE_HAL_SUBGHZ_REGISTER_CALLBACKS when set to 1
     allows the user to configure dynamically the driver callbacks.
     Use Functions @ref HAL_SUBGHZ_RegisterCallback() or @ref HAL_SUBGHZ_RegisterAddrCallback()
     to register an interrupt callback.

    [..]
     Function @ref HAL_SUBGHZ_RegisterCallback() allows to register following callbacks:
       (+) TxCpltCallback           : callback for Tx Completed.
       (+) RxCpltCallback           : callback for Rx Completed.
       (+) PreambleDetectedCallback : callback for Preamble detected.
       (+) SyncWordValidCallback    : callback for Synchro word valid.
       (+) HeaderValidCallback      : callback for Header valid.
       (+) HeaderErrorCallback      : callback for Header error.
       (+) CRCErrorCallback         : callback for CRC Error.
       (+) RxTxTimeoutCallback      : callback for Rx Tx Timeout.
       (+) 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.
    [..]
     For specific callback CADStatusCallback use dedicated register callbacks :
     @ref HAL_SUBGHZ_RegisterCadStatusCallback().
    [..]
     Use function @ref HAL_SUBGHZ_UnRegisterCallback to reset a callback to the default
     weak function.
     @ref HAL_SUBGHZ_UnRegisterCallback takes as parameters the HAL peripheral handle,
     and the Callback ID.
     This function allows to reset following callbacks:
       (+) TxCpltCallback           : callback for Tx Completed.
       (+) RxCpltCallback           : callback for Rx Completed.
       (+) PreambleDetectedCallback : callback for Preamble detected.
       (+) SyncWordValidCallback    : callback for Synchro word valid.
       (+) HeaderValidCallback      : callback for Header valid.
       (+) HeaderErrorCallback      : callback for Header error.
       (+) CRCErrorCallback         : callback for CRC Error.
       (+) RxTxTimeoutCallback      : callback for Rx Tx Timeout.
       (+) MspInitCallback          : callback for Msp Init.
       (+) MspDeInitCallback        : callback for Msp DeInit.
    [..]
     For specific callback CADStatusCallback use dedicated register callbacks :
     @ref HAL_SUBGHZ_UnRegisterCadStatusCallback().
    [..]
     MspInit and MspDeInit functions are reset to the legacy weak functions in the
     @ref HAL_SUBGHZ_Init()/ @ref HAL_SUBGHZ_DeInit() only when these callbacks are null
     (not registered beforehand).
     If MspInit or MspDeInit are not null, the @ref HAL_SUBGHZ_Init()/ @ref HAL_SUBGHZ_DeInit()
     keep and use the user MspInit/MspDeInit callbacks (registered beforehand) whatever the state.

    [..]
     Callbacks for MspInit/MspDeInit functions can be registered/unregistered
     in @ref HAL_SUBGHZ_STATE_READY or @ref HAL_SUBGHZ_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_SUBGHZ_RegisterCallback() before calling @ref HAL_SUBGHZ_DeInit()
     or @ref HAL_SUBGHZ_Init() function.

    [..]
     When the compilation flag USE_HAL_SUBGHZ_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.

 ===============================================================================
 [..]
    This subsection provides a set of functions allowing to manage the SUBGHZ
    data transfers.

    [..] The SUBGHZ supports Read and Write operation:

    (#) There are four modes of transfer:
       (++) Set operation: The Set Command operation is performed in polling mode.
            The HAL status of command processing is returned by the same function
            after finishing transfer.
       (++) Get operation: The Get Status operation is performed using polling mode
            These API update buffer in parameter to retrieve status of command.
            These API return the HAL status
       (++) Write operation: The write operation is performed in polling mode.
            The HAL status of all data processing is returned by the same function
            after finishing transfer.
       (++) Read operation: The read operation is performed using polling mode
            These APIs return the HAL status.

    (#) Blocking mode functions are :
        (++) HAL_SUBGHZ_ExecSetCmd(
        (++) HAL_SUBGHZ_ExecGetCmd()
        (++) HAL_SUBGHZ_WriteBuffer()
        (++) HAL_SUBGHZ_ReadBuffer()
        (++) HAL_SUBGHZ_WriteRegisters()
        (++) HAL_SUBGHZ_ReadRegisters()
        (++) HAL_SUBGHZ_WriteRegister()
        (++) HAL_SUBGHZ_ReadRegister()
