Data Fields
uint32_t	Channel	Specifies the peripheral channel. This parameter can be a value of CHANNEL This feature can be modified afterwards using unitary function LL_DMA_SetChannelSelection().
uint32_t	Direction	Specifies if the data will be transferred from memory to peripheral, from memory to memory or from peripheral to memory. This parameter can be a value of DIRECTION This feature can be modified afterwards using unitary function LL_DMA_SetDataTransferDirection().
uint32_t	FIFOMode	Specifies if the FIFO mode or Direct mode will be used for the specified stream. This parameter can be a value of DMA_LL_FIFOMODE Note The Direct mode (FIFO mode disabled) cannot be used if the memory-to-memory data transfer is configured on the selected stream This feature can be modified afterwards using unitary functions LL_DMA_EnableFifoMode() or LL_DMA_EnableFifoMode() .
uint32_t	FIFOThreshold	Specifies the FIFO threshold level. This parameter can be a value of FIFOTHRESHOLD This feature can be modified afterwards using unitary function LL_DMA_SetFIFOThreshold().
uint32_t	MemBurst	Specifies the Burst transfer configuration for the memory transfers. It specifies the amount of data to be transferred in a single non interruptible transaction. This parameter can be a value of MBURST Note The burst mode is possible only if the address Increment mode is enabled. This feature can be modified afterwards using unitary function LL_DMA_SetMemoryBurstxfer().
uint32_t	MemoryOrM2MDstAddress	Specifies the memory base address for DMA transfer or as Destination base address in case of memory to memory transfer direction. This parameter must be a value between Min_Data = 0 and Max_Data = 0xFFFFFFFF.
uint32_t	MemoryOrM2MDstDataSize	Specifies the Memory data size alignment or Destination data size alignment (byte, half word, word) in case of memory to memory transfer direction. This parameter can be a value of MDATAALIGN This feature can be modified afterwards using unitary function LL_DMA_SetMemorySize().
uint32_t	MemoryOrM2MDstIncMode	Specifies whether the Memory address or Destination address in case of memory to memory transfer direction is incremented or not. This parameter can be a value of MEMORY This feature can be modified afterwards using unitary function LL_DMA_SetMemoryIncMode().
uint32_t	Mode	Specifies the normal or circular operation mode. This parameter can be a value of MODE Note The circular buffer mode cannot be used if the memory to memory data transfer direction is configured on the selected Stream This feature can be modified afterwards using unitary function LL_DMA_SetMode().
uint32_t	NbData	Specifies the number of data to transfer, in data unit. The data unit is equal to the source buffer configuration set in PeripheralSize or MemorySize parameters depending in the transfer direction. This parameter must be a value between Min_Data = 0 and Max_Data = 0x0000FFFF This feature can be modified afterwards using unitary function LL_DMA_SetDataLength().
uint32_t	PeriphBurst	Specifies the Burst transfer configuration for the peripheral transfers. It specifies the amount of data to be transferred in a single non interruptible transaction. This parameter can be a value of PBURST Note The burst mode is possible only if the address Increment mode is enabled. This feature can be modified afterwards using unitary function LL_DMA_SetPeriphBurstxfer().
uint32_t	PeriphOrM2MSrcAddress	Specifies the peripheral base address for DMA transfer or as Source base address in case of memory to memory transfer direction. This parameter must be a value between Min_Data = 0 and Max_Data = 0xFFFFFFFF.
uint32_t	PeriphOrM2MSrcDataSize	Specifies the Peripheral data size alignment or Source data size alignment (byte, half word, word) in case of memory to memory transfer direction. This parameter can be a value of PDATAALIGN This feature can be modified afterwards using unitary function LL_DMA_SetPeriphSize().
uint32_t	PeriphOrM2MSrcIncMode	Specifies whether the Peripheral address or Source address in case of memory to memory transfer direction is incremented or not. This parameter can be a value of PERIPH This feature can be modified afterwards using unitary function LL_DMA_SetPeriphIncMode().
uint32_t	Priority	Specifies the channel priority level. This parameter can be a value of PRIORITY This feature can be modified afterwards using unitary function LL_DMA_SetStreamPriorityLevel().
