Detailed Description

Initialization and de-initialization functions.

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

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

      (+) Call the function hal_hmac_init() to configure the selected device with
          the selected configuration:
        (++) mode
        (++) key
        (++) user_hash
        (++) dpa_mode

      (+) Call the function hal_hmac_deinit() to restore the default configuration
          of the selected HMACx peripheral.

Function Documentation

hal_hmac_deinit()

hal_status_t hal_hmac_deinit

(

hmac_handle_t *

p_hmac

)

De-initialize the HMAC peripheral.

Parameters

[in]

p_hmac

Pointer to a HMAC handle which contains the configuration information for the specified HMAC 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_hmac_init()

hal_status_t hal_hmac_init

(

hmac_handle_t *

p_hmac

)

Initialize the HMAC according to the specified parameters in the hmac_init_t and initialize the associated handle.

Parameters

[in]

p_hmac

Pointer to a HMAC handle which contains the configuration information for the specified HMAC 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_hmac_msp_deinit()

void hal_hmac_msp_deinit

(

hmac_handle_t *

p_hmac

)

De-initialize the HMAC MSP.

Note

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

Parameters

[in]

p_hmac

Pointer to a HMAC handle which contains the configuration information for the specified HMAC module.

hal_hmac_msp_init()

void hal_hmac_msp_init

(

hmac_handle_t *

p_hmac

)

Initialize the HMAC MSP.

Note

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

Parameters

[in]

p_hmac

Pointer to a HMAC handle which contains the configuration information for the specified HMAC module.
