void DAC_ClearFlag	(	DAC_Channel_TypeDef	DAC_Channel,
		DAC_FLAG_TypeDef	DAC_FLAG
	)

Clears the DAC channel's pending flags.

Parameters:

DAC_Channel,:	the selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
DAC_FLAG,:	specifies the flag to clear. This parameter can be of the following value: DAC_FLAG_DMAUDR: DMA underrun flag

Return values:

None

Definition at line 736 of file stm8l15x_dac.c.

References DAC, IS_DAC_CHANNEL, and IS_DAC_FLAG.

void DAC_ClearITPendingBit	(	DAC_Channel_TypeDef	DAC_Channel,
		DAC_IT_TypeDef	DAC_IT
	)

Clears the DAC channel's interrupt pending bits.

Parameters:

DAC_Channel,:	the selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
DAC_IT,:	specifies the DAC interrupt pending bit to clear. This parameter can be the following values: DAC_IT_DMAUDR: DMA underrun interrupt mask

Return values:

None

Definition at line 807 of file stm8l15x_dac.c.

References DAC, IS_DAC_CHANNEL, and IS_DAC_IT.

FlagStatus DAC_GetFlagStatus	(	DAC_Channel_TypeDef	DAC_Channel,
		DAC_FLAG_TypeDef	DAC_FLAG
	)

Checks whether the specified DAC flag is set or not.

Parameters:

DAC_Channel,:	thee selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
DAC_FLAG,:	specifies the flag to check. This parameter can be only of the following value: DAC_FLAG_DMAUDR: DMA underrun flag

Note:

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Return values:

The	new state of DAC_FLAG (SET or RESET).

References DAC, IS_DAC_CHANNEL, IS_DAC_FLAG, RESET, and SET.

ITStatus DAC_GetITStatus	(	DAC_Channel_TypeDef	DAC_Channel,
		DAC_IT_TypeDef	DAC_IT
	)

Checks whether the specified DAC interrupt has occurred or not.

Parameters:

DAC_Channel,:	the selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
DAC_IT,:	specifies the DAC interrupt source to check. This parameter can be the following values: DAC_IT_DMAUDR: DMA underrun interrupt mask

Note:

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Return values:

The	new state of DAC_IT (SET or RESET).

void DAC_ITConfig	(	DAC_Channel_TypeDef	DAC_Channel,
		DAC_IT_TypeDef	DAC_IT,
		FunctionalState	NewState
	)

Enables or disables the specified DAC interrupts.

Parameters:

DAC_Channel,:	the selected DAC channel. This parameter can be one of the following values: DAC_Channel_1: DAC Channel1 selected DAC_Channel_2: DAC Channel2 selected
DAC_IT,:	specifies the DAC interrupt sources to be enabled or disabled. This parameter can be the following values: DAC_IT_DMAUDR: DMA underrun interrupt mask

Note:

The DMA underrun occurs when a second external trigger arrives before the acknowledgement for the first external trigger is received (first request).

Parameters:

NewState,:

new state of the specified DAC interrupts. This parameter can be: ENABLE or DISABLE.

Return values:

None
