HAL RNG constants migration

This section provides information about the HAL RNG constants migration.

HAL RNG error code constants

HAL1

HAL2 

#define  HAL_RNG_ERROR_NONE
#define  HAL_RNG_ERROR_SEED
#define  HAL_RNG_ERROR_CLOCK


#define  HAL_RNG_ERROR_INVALID_CALLBACK
#define  HAL_RNG_ERROR_TIMEOUT
#define  HAL_RNG_ERROR_BUSY
#define  HAL_RNG_ERROR_RECOVERSEED

#define HAL_RNG_ERROR_NONE
#define HAL_RNG_ERROR_SEED
#define HAL_RNG_ERROR_CLOCK


Removed; these kinds of logical errors are reported by direct function return.

HAL RNG automatic reset state constants

HAL1

HAL2

In HAL1, the RNG automatic reset state is encapsulated as a member of the RNG_ConfigTypeDef structure.

Removed: In HAL2, the RNG automatic reset state is managed through dedicated functions within the HAL layer.

For more details, refer to HAL RNG configuration type definition. 

#define RNG_ARDIS_ENABLE
#define RNG_ARDIS_DISABLE

HAL_RNG_EnableAutoReset()
HAL_RNG_DisableAutoReset()

HAL RNG interrupt constants

The listed defines in HAL1 are used by : HAL RNG get IT, and HAL RNG clear interrupt flags.

All RNG interrupt status flag definitions and macros are removed from HAL2.

HAL1

HAL2 

#define RNG_IT_DRDY

Removed; use LL_RNG_IsActiveFlag_DRDY. 

#define RNG_IT_CEI

Removed; use LL_RNG_IsActiveFlag_CEIS / LL_RNG_ClearFlag_CEIS. 

#define RNG_IT_SEI

Removed; use LL_RNG_IsActiveFlag_SEIS / LL_RNG_ClearFlag_SEIS.

HAL RNG flag constants

The listed defines in HAL1 are used by : HAL RNG get flag.

All RNG flag definitions and macros are removed from HAL2.

HAL1

HAL2 

#define RNG_FLAG_DRDY

Removed; use LL_RNG_IsActiveFlag_DRDY. 

#define RNG_FLAG_CECS

Removed; use LL_RNG_IsActiveFlag_CECS. 

#define RNG_FLAG_SECS

Removed; use LL_RNG_IsActiveFlag_SECS.
