Field Documentation
 uint32_t DMA_InitTypeDef::DMA_PeripheralBaseAddr
 Specifies the peripheral base address for DMAy Channelx.
 uint32_t DMA_InitTypeDef::DMA_MemoryBaseAddr
 Specifies the memory base address for DMAy Channelx.
 uint32_t DMA_InitTypeDef::DMA_DIR
 Specifies if the peripheral is the source or destination. This parameter can be a
value of DMA_data_transfer_direction
 uint16_t DMA_InitTypeDef::DMA_BufferSize
 Specifies the buffer size, in data unit, of the specified Channel. The data unit is
equal to the configuration set in DMA_PeripheralDataSize or
DMA_MemoryDataSize members depending in the transfer direction.
 uint32_t DMA_InitTypeDef::DMA_PeripheralInc
 Specifies whether the Peripheral address register is incremented or not. This
parameter can be a value of DMA_peripheral_incremented_mode
 uint32_t DMA_InitTypeDef::DMA_MemoryInc
 Specifies whether the memory address register is incremented or not. This
parameter can be a value of DMA_memory_incremented_mode
 uint32_t DMA_InitTypeDef::DMA_PeripheralDataSize
 Specifies the Peripheral data width. This parameter can be a value of
DMA_peripheral_data_size
 uint32_t DMA_InitTypeDef::DMA_MemoryDataSize
 Specifies the Memory data width. This parameter can be a value of
DMA_memory_data_size
 uint32_t DMA_InitTypeDef::DMA_Mode
 Specifies the operation mode of the DMAy Channelx. This parameter can be a
value of DMA_circular_normal_mode
 uint32_t DMA_InitTypeDef::DMA_Priority
 Specifies the software priority for the DMAy Channelx. This parameter can be a
value of DMA_priority_level
 uint32_t DMA_InitTypeDef::DMA_M2M
 Specifies if the DMAy Channelx will be used in memory-to-memory transfer. This
parameter can be a value of DMA_memory_to_memory
