Note:The Direct mode (FIFO mode disabled) cannot be used if the memory-to-
memory data transfer is configured on the selected stream
uint32_t DMA_InitTypeDef::FIFOThreshold
Specifies the FIFO threshold level. This parameter can be a value of
DMA_FIFO_threshold_level
uint32_t DMA_InitTypeDef::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 DMA_Memory_burst
Note:The burst mode is possible only if the address Increment mode is enabled.
uint32_t DMA_InitTypeDef::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 DMA_Peripheral_burst
Note:The burst mode is possible only if the address Increment mode is enabled.
