Fields

PeriphOrM2MSrcAddress: u32

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.

MemoryOrM2MDstAddress: u32

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.

Direction: u32

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 [DMA_LL_EC_DIRECTION] This feature can be modified afterwards using unitary function [LL_DMA_SetDataTransferDirection()]

Mode: u32

Specifies the normal or circular operation mode. This parameter can be a value of [DMA_LL_EC_MODE] data transfer direction is configured on the selected Channel This feature can be modified afterwards using unitary function [LL_DMA_SetMode()]

Notes

• The circular buffer mode cannot be used if the memory to memory

PeriphOrM2MSrcIncMode: u32

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 [DMA_LL_EC_PERIPH] This feature can be modified afterwards using unitary function [LL_DMA_SetPeriphIncMode()]

MemoryOrM2MDstIncMode: u32

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 [DMA_LL_EC_MEMORY] This feature can be modified afterwards using unitary function [LL_DMA_SetMemoryIncMode()]

PeriphOrM2MSrcDataSize: u32

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 [DMA_LL_EC_PDATAALIGN] This feature can be modified afterwards using unitary function [LL_DMA_SetPeriphSize()]

MemoryOrM2MDstDataSize: u32

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 [DMA_LL_EC_MDATAALIGN] This feature can be modified afterwards using unitary function [LL_DMA_SetMemorySize()]

NbData: u32

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()]

PeriphRequest: u32

Specifies the peripheral request. This parameter can be a value of [DMAMUX_LL_EC_REQUEST] This feature can be modified afterwards using unitary function [LL_DMA_SetPeriphRequest()]

Priority: u32

Specifies the channel priority level. This parameter can be a value of [DMA_LL_EC_PRIORITY] This feature can be modified afterwards using unitary function [LL_DMA_SetChannelPriorityLevel()]
