Function Name
void DAC_ClearFlag ( uint32_t DAC_Channel, uint32_t
DAC_FLAG)
Function Description
Clears the DAC channel's pending flags.
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 clear. This parameter can
be of the following value:
 DAC_FLAG_DMAUDR : DMA underrun flag
Return values
 None.

7.2.8.4 DAC_GetITStatus
Function Name
ITStatus DAC_GetITStatus ( uint32_t DAC_Channel, uint32_t
DAC_IT)
Function Description
Checks whether the specified DAC interrupt has occurred 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_IT : specifies the DAC interrupt source to check. This
parameter can be the following values:
 DAC_IT_DMAUDR : DMA underrun interrupt mask
Return values
 The new state of DAC_IT (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).
