 DMA1_FLAG_TE1 : DMA1 Channel1 transfer error flag.
 DMA1_FLAG_GL2 : DMA1 Channel2 global flag.
 DMA1_FLAG_TC2 : DMA1 Channel2 transfer complete
flag.
 DMA1_FLAG_HT2 : DMA1 Channel2 half transfer flag.
 DMA1_FLAG_TE2 : DMA1 Channel2 transfer error flag.
 DMA1_FLAG_GL3 : DMA1 Channel3 global flag.
 DMA1_FLAG_TC3 : DMA1 Channel3 transfer complete
flag.
 DMA1_FLAG_HT3 : DMA1 Channel3 half transfer flag.
 DMA1_FLAG_TE3 : DMA1 Channel3 transfer error flag.
 DMA1_FLAG_GL4 : DMA1 Channel4 global flag.
 DMA1_FLAG_TC4 : DMA1 Channel4 transfer complete
flag.
 DMA1_FLAG_HT4 : DMA1 Channel4 half transfer flag.
 DMA1_FLAG_TE4 : DMA1 Channel4 transfer error flag.
 DMA1_FLAG_GL5 : DMA1 Channel5 global flag.
 DMA1_FLAG_TC5 : DMA1 Channel5 transfer complete
flag.
 DMA1_FLAG_HT5 : DMA1 Channel5 half transfer flag.
 DMA1_FLAG_TE5 : DMA1 Channel5 transfer error flag.
 DMA1_FLAG_GL6 : DMA1 Channel6 global flag.
 DMA1_FLAG_TC6 : DMA1 Channel6 transfer complete
flag.
 DMA1_FLAG_HT6 : DMA1 Channel6 half transfer flag.
 DMA1_FLAG_TE6 : DMA1 Channel6 transfer error flag.
 DMA1_FLAG_GL7 : DMA1 Channel7 global flag.
 DMA1_FLAG_TC7 : DMA1 Channel7 transfer complete
flag.
