Detailed Description

Initialization and Configuration functions.

 ===============================================================================
              ##### Initialization and de-initialization functions #####
 ===============================================================================
    [..]  This subsection provides a set of functions allowing to initialize and
          de-initialize the AESx peripheral:

      (+) User must implement hal_aes_msp_init() function in which he configures
          all related peripherals resources (GPIO, DMA, IT and NVIC ).

      (+) Call the function hal_aes_init() to configure the selected device with
          the selected configuration:
        (++) Key Size
        (++) operation_mode
        (++) ChainingMode
        (++) key
        (++) init_vector
        (++) DPAMode
        (++) Seed

      (+) Call the function hal_aes_deinit() to restore the default configuration
          of the selected AESx peripheral.

Function Documentation

hal_aes_deinit()

hal_status_t hal_aes_deinit

(

aes_handle_t *

p_aes

)

De-initialize the AES peripheral.

Parameters

[in]

p_aes

Pointer to an AES handle which contains the configuration information for the specified AES module.

Return values

HAL_OK	Operation is OK.
HAL_ERROR	Parameter error or operation not supported.
HAL_BUSY	Driver is busy.
HAL_TIMEOUT	Timeout occurred.

hal_aes_init()

hal_status_t hal_aes_init

(

aes_handle_t *

p_aes

)

Initialize the AES according to the specified parameters in the aes_init_t and initialize the associated handle.

Parameters

[in]

p_aes

Pointer to an AES handle which contains the configuration information for the specified AES module.

Return values

HAL_OK	Operation is OK.
HAL_ERROR	Parameter error or operation not supported.
HAL_BUSY	Driver is busy.
HAL_TIMEOUT	Timeout occurred.

hal_aes_msp_deinit()

void hal_aes_msp_deinit

(

aes_handle_t *

p_aes

)

De-initialize the AES MSP.

Note

This function should not be modified. When the callback is needed, the hal_aes_msp_deinit can be implemented in the user file.

Parameters

[in]

p_aes

Pointer to an AES handle which contains the configuration information for the specified AES module.

hal_aes_msp_init()

void hal_aes_msp_init

(

aes_handle_t *

p_aes

)

Initialize the AES MSP.

Note

This function should not be modified. When the callback is needed, the hal_aes_msp_deinit can be implemented in the user file.

Parameters

[in]

p_aes

Pointer to an AES handle which contains the configuration information for the specified AES module.
