This value provides User Application 4 field space for S2MM received status on the Status Stream.
Figure 1. S2MM_APP4
| Bits | Field Name | Description |
|---|---|---|
| 31 to 0 | APP4/RxLength | User Application field 4 and Receive Byte Length. If Use RxLength
In Status Stream is not enabled, this field functions identically to
APP0 to APP3 in that the status data received on the AXI Status
Stream is stored into the APP4 field of the End of Frame (EOF)
Descriptor. This field has a dual purpose when Use RxLength in Status Stream is enabled. The first least significant bits specified in the Buffer Length Register Width specify the total number of receive bytes for a packet that were received on the S2MM primary data stream. Second, the remaining most significant bits are User Application data. |
