__HAL_RNG_RESET_HANDLE_STATE Description:

Reset RNG handle state.

Parameters:

__HANDLE__: RNG Handle

Return value:

UM1725		HAL RNG Generic Driver
		None
__HAL_RNG_DISABLE	Description:
	Disables the RNG peripheral.
	Parameters:
		__HANDLE__: RNG Handle
	Return value:
		None
__HAL_RNG_GET_FLAG	Description:
	Check the selected RNG flag status.
	Parameters:
		__HANDLE__: RNG Handle
	__FLAG__: 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 value:
	The: new state of __FLAG__ (SET or
		RESET).
__HAL_RNG_CLEAR_FLAG	Description:
	Clears the selected RNG flag status.
	Parameters:
		__HANDLE__: RNG handle
	__FLAG__: RNG flag to clear
	Return value:
		None
	Notes:
	WARNING: This is a dummy macro for
		HAL code alignment, flags
		RNG_FLAG_DRDY, RNG_FLAG_CECS
		and RNG_FLAG_SECS are read-only.
__HAL_RNG_ENABLE_IT	Description:
	Enables the RNG interrupts.
	Parameters:
		__HANDLE__: RNG Handle
	Return value:
		None
__HAL_RNG_DISABLE_IT	Description:
DOCID025834 Rev 2			611/900

HAL RNG Generic Driver		UM1725
	Disables the RNG interrupts.
	Parameters:
		__HANDLE__: RNG Handle
	Return value:
		None
__HAL_RNG_GET_IT	Description:
	Checks whether the specified RNG
		interrupt has occurred or not.
	Parameters:
		__HANDLE__: RNG Handle
	__INTERRUPT__: 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 value:
	The: new state of __INTERRUPT__ (SET
		or RESET).
__HAL_RNG_CLEAR_IT	Description:
	Clear the RNG interrupt status flags.
	Parameters:
		__HANDLE__: RNG Handle
	__INTERRUPT__: 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
	Return value:
		None
	Notes:

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