| Bits | Name | Description |
|---|---|---|
| 31:5 | Descriptor Write Address | The 32 byte aligned location to write an inbound descriptor |
| 2 | Write Descriptor | If set to 1, a descriptor will be generated when the client completes a frame. |
| 1 | Drop Data | If set to 1, the data will not be written out. Also, if this is set, the write descriptor bit must be set. This allows for descriptors to only be written out so that software can determine the size of the required buffer before data is written out. |
| 0 | Use Descriptor Register | If set to 1, the CURRENT_DESCRIPTOR register will be used for the write address location. If set to 0, the Descriptor Write Address field in this word will be used for the Descriptor Write Address. |
