Return values
 None.
Notes
 Clearing the Global flag (DMAy_FLAG_GLx) results in
clearing all other flags relative to the same channel (Transfer
Complete, Half-transfer Complete and Transfer Error flags:
DMAy_FLAG_TCx, DMAy_FLAG_HTx and
DMAy_FLAG_TEx).
9.2.7.4 DMA_GetITStatus
Function Name
ITStatus DMA_GetITStatus ( uint32_t DMAy_IT)
Function Description
Checks whether the specified DMAy Channelx interrupt has
occurred or not.
Parameters
 DMAy_IT : specifies the DMAy interrupt source to check.
This parameter can be one of the following values:
 DMA1_IT_GL1 : DMA1 Channel1 global interrupt.
 DMA1_IT_TC1 : DMA1 Channel1 transfer complete
interrupt.
 DMA1_IT_HT1 : DMA1 Channel1 half transfer interrupt.
 DMA1_IT_TE1 : DMA1 Channel1 transfer error
interrupt.
 DMA1_IT_GL2 : DMA1 Channel2 global interrupt.
 DMA1_IT_TC2 : DMA1 Channel2 transfer complete
interrupt.
