uint32_t LL_DMA_InitTypeDef::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 LL_DMA_InitTypeDef::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 LL_DMA_InitTypeDef::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
DMA_LL_EC_DIRECTIONThis feature can be modified afterwards using unitary
function LL_DMA_SetDataTransferDirection().
uint32_t LL_DMA_InitTypeDef::Mode
Specifies the normal or circular operation mode. This parameter can be a value of
DMA_LL_EC_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 LL_DMA_InitTypeDef::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
DMA_LL_EC_PERIPHThis feature can be modified afterwards using unitary function
LL_DMA_SetPeriphIncMode().
uint32_t LL_DMA_InitTypeDef::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
