7.2.8 Interrupts and flags management functions
7.2.8.1 DAC_ITConfig
Function Name
void DAC_ITConfig ( uint32_t DAC_Channel, uint32_t DAC_IT,
FunctionalState NewState)
Function Description
Enables or disables the specified DAC interrupts.
Parameters
 DAC_Channel : The selected DAC channel. This parameter
can be:
 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
Parameters
 NewState : new state of the specified DAC interrupts. This
parameter can be: ENABLE or DISABLE.
Return values
 None.
Notes
 The DMA underrun occurs when a second external trigger
arrives before the acknowledgement for the first external
trigger is received (first request).
7.2.8.2 DAC_GetFlagStatus
Function Name
FlagStatus DAC_GetFlagStatus ( uint32_t DAC_Channel,
uint32_t DAC_FLAG)
Function Description
Checks whether the specified DAC flag is set or not.
Parameters
 DAC_Channel : The selected DAC channel. This parameter
can be:
 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
Return values
 The new state of DAC_FLAG (SET or RESET).
Notes
 The DMA underrun occurs when a second external trigger
arrives before the acknowledgement for the first external
trigger is received (first request).
