| Interface Name* | Type | Description | 
|---|---|---|
| d2hdm_desc | AVST Sink | D2H data mover gets the descriptor from external descriptor controller. This interface is also used to send the DMWr or DWIntr command (MM_mode=0) to send the writeback to host. | 
| d2hdm_desc_status | AVST Source | Once a descriptor is complete, D2H data mover returns the status of the D2H descriptors. | 
| d2hdm_master | AVMM Read Master | D2H data mover reads the data from local memory and writes the data to host memory location. |
