                    ##### AES extended suspension and resumption functions #####
  ==============================================================================
    [..]  This section provides functions allowing to:
      (+) save in memory the Initialization Vector, the Key registers, the Control register or
          the Suspend registers when a process is suspended by a higher priority message
      (+) write back in CRYP hardware block the saved values listed above when the suspended
          lower priority message processing is resumed.

void HAL_CRYPEx_ProcessSuspend ( CRYP_HandleTypeDef * hcryp )

Request CRYP processing suspension when in polling or interruption mode.

Parameters:

hcryp pointer to a CRYP_HandleTypeDef structure that contains the configuration information for CRYP module.

Note:: Set the handle field SuspendRequest to the appropriate value so that the on-going CRYP processing is suspended as soon as the required conditions are met.; It is advised not to suspend the CRYP processing when the DMA controller is managing the data transfer

Return values:

None

void HAL_CRYPEx_Read_ControlRegister	(	CRYP_HandleTypeDef *	hcryp,
		uint8_t *	Output
	)

In case of message GCM/GMAC (CCM/CMAC when applicable) processing suspension, read the Control Register.

Parameters:

hcryp	pointer to a CRYP_HandleTypeDef structure that contains the configuration information for CRYP module.
Output	Pointer to the buffer containing the saved Control Register.

Note:: This values has to be stored for reuse by writing back the AES_CR register as soon as the interrupted processing has to be resumed.

Return values:

None

void HAL_CRYPEx_Read_IVRegisters	(	CRYP_HandleTypeDef *	hcryp,
		uint8_t *	Output
	)

In case of message processing suspension, read the Initialization Vector.

Parameters:

hcryp	pointer to a CRYP_HandleTypeDef structure that contains the configuration information for CRYP module.
Output	Pointer to the buffer containing the saved Initialization Vector.

Note:: This value has to be stored for reuse by writing the AES_IVRx registers as soon as the interrupted processing has to be resumed. Applicable to all chaining modes.; AES must be disabled when reading or resetting the IV values.

Return values:

None

Parameters:

hcryp	pointer to a CRYP_HandleTypeDef structure that contains the configuration information for CRYP module.
Output	Pointer to the buffer containing the saved Key Registers.
KeySize	Indicates the key size (128 or 256 bits).

Note:: These values have to be stored for reuse by writing back the AES_KEYRx registers as soon as the interrupted processing has to be resumed.

Return values:

None
