STM32CUBE配置AD的DMA请求，怎么配置数据寄存器地址和存储器地址？

用CUBE配置DMA的时候，
hdma_adc1.Instance = DMA1_Channel1;
    hdma_adc1.Init.Direction = DMA_PERIPH_TO_MEMORY;
    hdma_adc1.Init.PeriphInc = DMA_PINC_DISABLE;
    hdma_adc1.Init.MemInc = DMA_MINC_ENABLE;
    hdma_adc1.Init.PeriphDataAlignment = DMA_PDATAALIGN_HALFWORD;
    hdma_adc1.Init.MemDataAlignment = DMA_MDATAALIGN_HALFWORD;
    hdma_adc1.Init.Mode = DMA_CIRCULAR;
    hdma_adc1.Init.Priority = DMA_PRIORITY_HIGH;

可以看到并没有配置DMA外设基地址和内部基地址，也没有配置DMA通道的DMA缓存大小？
可以看到例子中是有这个配置的，

HAL_ADC_Start_DMA(&hadc1, (uint32_t*)&ADC_Buffer, 30);这句函数里面有句话是
  HAL_DMA_Start_IT(hadc->DMA_Handle, (uint32_t)&hadc->Instance->DR, (uint32_t)pData, Length);
而HAL_DMA_Start_IT的参数是
@param  hdma: pointer to a DMA_HandleTypeDef structure that contains
  *               the configuration information for the specified DMA Channel.
  * @param  SrcAddress: The source memory Buffer address
  * @param  DstAddress: The destination memory Buffer address
  * @param  DataLength: The length of data to be transferred from source to destination
难道是这句话？
ADC_Buffer对应pData这个是DMA地址？hadc->Instance->DR对应外设ADC基地址，Length对应例子中的DMA_BufferSize.
