ZDMA_CH_DSCR_ATTR (ZDMA) Register Bit-Field Summary
Field Name | Bits | Type | Reset Value | Description |
---|---|---|---|---|
Reserved | 31:9 | razRead as zero | 0x0 | Reserved for future use |
AXCOHRNT | 8 | rwNormal read/write | 0x0 | This field is only valid for LPD DMA. FPD DMA does not support coherency at descriptor and data. 0: AXI transactions generated for the descriptor read are marked Non-coherent. 1: AXI transactions generated for the descriptor read are marked coherent. |
AXCACHE | 7:4 | rwNormal read/write | 0x0 | AXI cache bit used for DSCR fetch (both on SRC and DST Side). |
AXQOS | 3:0 | rwNormal read/write | 0x0 | QoS bit used for DSCR fetch (both on SRC and DST side). |
