Detailed Description

Macro Definition Documentation

#define __HAL_RNG_CLEAR_FLAG	(		__HANDLE__,
			__FLAG__
	)		/* dummy macro */

Clears the selected RNG flag status.

Parameters

<strong>HANDLE</strong>	RNG handle
<strong>FLAG</strong>	RNG flag to clear

Note

WARNING: This is a dummy macro for HAL code alignment, flags RNG_FLAG_DRDY, RNG_FLAG_CECS and RNG_FLAG_SECS are read-only.

Return values

None

Definition at line 181 of file stm32f7xx_hal_rng.h.

#define __HAL_RNG_CLEAR_IT	(		__HANDLE__,
			__INTERRUPT__
	)		(((__HANDLE__)->Instance->SR) = ~(__INTERRUPT__))

Clear the RNG interrupt status flags.

Parameters

<strong>HANDLE</strong>	RNG Handle
<strong>INTERRUPT</strong>	specifies the RNG interrupt status flag to clear. This parameter can be one of the following values: RNG_IT_CEI: Clock error interrupt RNG_IT_SEI: Seed error interrupt

Note

RNG_IT_DRDY flag is read-only, reading RNG_DR register automatically clears RNG_IT_DRDY.

Return values

None

Definition at line 221 of file stm32f7xx_hal_rng.h.

(

__HANDLE__

)

((__HANDLE__)->Instance->CR &= ~RNG_CR_RNGEN)

#define __HAL_RNG_GET_FLAG	(		__HANDLE__,
			__FLAG__
	)		(((__HANDLE__)->Instance->SR & (__FLAG__)) == (__FLAG__))

Check the selected RNG flag status.

Parameters

<strong>HANDLE</strong>	RNG Handle
<strong>FLAG</strong>	RNG flag This parameter can be one of the following values: RNG_FLAG_DRDY: Data ready RNG_FLAG_CECS: Clock error current status RNG_FLAG_SECS: Seed error current status

Return values

#define __HAL_RNG_GET_IT	(		__HANDLE__,
			__INTERRUPT__
	)		(((__HANDLE__)->Instance->SR & (__INTERRUPT__)) == (__INTERRUPT__))

Checks whether the specified RNG interrupt has occurred or not.

Parameters

<strong>HANDLE</strong>	RNG Handle
<strong>INTERRUPT</strong>	specifies the RNG interrupt status flag to check. This parameter can be one of the following values: RNG_IT_DRDY: Data ready interrupt RNG_IT_CEI: Clock error interrupt RNG_IT_SEI: Seed error interrupt

Return values

The	new state of INTERRUPT (SET or RESET).
