AXISTEN_IF_ENABLE_CLIENT_TAG (CPM4_PCIE1_ATTR) Register Description
| Register Name | AXISTEN_IF_ENABLE_CLIENT_TAG |
|---|---|
| Relative Address | 0x0000000074 |
| Absolute Address | 0x00FCA60074 (CPM4_PCIE1_ATTR) |
| Width | 32 |
| Type | rwNormal read/write |
| Reset Value | 0x00000000 |
| Description | AXI Streaming Enhanced Inteface Tag management option for RQ interface: When this attribute is FALSE, Tag management for Non-Posted transactions initiated from the requester request interface is performed by the PCIe Hard Block. That is, for each Non-Posted request, the core allocates the Tag for the transaction and communicates it to the client.When this attribute set to TRUE, internal tag management is disabled, allowing the user to supply the tag to be used for each request. The user must present the Tag field in the Request descriptor header in the range 0-31 when attribute PF0_DEV_CAP_EXT_TAG_SUPPORTED is FALSE, while Tag field must be in the range 0-255 when attribute PF0_DEV_CAP_EXT_TAG_SUPPORTED is TRUE. When this attribute is TURE and attribute PF0_DEV_CAP_EXT_TAG_SUPPORTED is TRUE, attribute AXISTEN_IF_ENABLE_256_TAGS should be set to TRUE. |
This register should only be written to during reset of the PCIe block
