ETH_DMAConfigTypeDef struct

Sets the arbitration scheme between DMA Tx and Rx This parameter can be a value of ETH_DMA_Arbitration.

Enables or disables the AHB Master interface address aligned burst transfers on Read and Write channels.

Sets the AHB Master interface burst transfers. This parameter can be a value of ETH_Burst_Mode.

Selects or not the Dropping of TCP/IP Checksum Error Frames.

Enables or disables the Receive store and forward mode.

Enables or disables Transmit store and forward mode.

Indicates the maximum number of beats to be transferred in one Tx DMA transaction. This parameter can be a value of ETH_Tx_DMA_Burst_Length.

Selects or not the Transmit Threshold Control. This parameter can be a value of ETH_Transmit_Threshold_Control.

Indicates the maximum number of beats to be transferred in one Rx DMA transaction. This parameter can be a value of ETH_Rx_DMA_Burst_Length.

Selects or not the forward to the DMA of erroneous frames.

Enables or disables the Rx Packet Flush.

Enables or disables the Rx FIFO to forward Undersized frames (frames with no Error and length less than 64 bytes) including pad-bytes and CRC).

Selects the threshold level of the Receive FIFO. This parameter can be a value of ETH_Receive_Threshold_Control.

Selects or not the Operate on second frame mode, which allows the DMA to process a second frame of Transmit data even before obtaining the status for the first frame.

Enables the enhanced descriptor format.

Specifies the number of word to skip between two unchained descriptors (Ring mode) This parameter must be a number between Min_Data = 0 and Max_Data = 32.
