void DAC_ITConfig ( uint32_t DAC_Channel, uint32_t DAC_IT,
FunctionalState NewState)
Enables or disables the specified DAC interrupts.

DAC_Channel : The selected DAC channel. This parameter
can be:

DAC_Channel_1 :

DAC_Channel_2 :

DAC_IT : specifies the DAC interrupt sources to be enabled
or disabled. This parameter can be the following values:

DAC_IT_DMAUDR :

NewState : new state of the specified DAC interrupts. This
parameter can be: ENABLE or DISABLE.

None.

The DMA underrun occurs when a second external trigger
arrives before the acknowledgement for the first external
trigger is received (first request).
FlagStatus DAC_GetFlagStatus ( uint32_t DAC_Channel,
uint32_t DAC_FLAG)
Checks whether the specified DAC flag is set or not.

DAC_Channel : The selected DAC channel. This parameter
can be:

DAC_Channel_1 :

DAC_Channel_2 :

DAC_FLAG : specifies the flag to check. This parameter can
be only of the following value:

DAC_FLAG_DMAUDR :

The new state of DAC_FLAG (SET or RESET).

The DMA underrun occurs when a second external trigger
arrives before the acknowledgement for the first external
trigger is received (first request).
