User Guide
UNSUPPORT_TRAN_EN [22] RW
Enable reporting of an unsupported transaction error. Save
and lock transaction capture information in
Logical/Transport Layer Device ID and Control Capture
CSRs. User logic must provide the correct capture
information on the appropriate input signals when
assserting the unsupported_transaction_set input
port.
1'b0
MISSING_DATA_STRM_
CNTXT_EN
[21] RW
Enable reporting of a continuation or end data streaming
segment for a closed or non-existent segmentation context.
Save and lock capture information in the appropriate
Logical/Transport Layer Control Capture CSRs. User logic
must provide the correct capture information on the
appropriate input signals when assserting the
missing_data_streaming_context_set
input port.
1'b0
OPEN_EXSTG_DATA_STRM_
CNTXT_EN
[20] RW
Enable reporting of an initial or single data streaming
segment for an already-open segmentation context. Save
and lock capture information in the appropriate
Logical/Transport Layer Control Capture CSRs. User logic
must provide the correct capture information on the
appropriate input signals when assserting the
open_existing_data_streaming_context_set
input
port.
1'b0
LONG_DATA_STRM_SGMNT_EN [19] RW
Enable reporting of a data streaming segment with a payload
size greater than the MTU. Save and lock capture
information in the appropriate Logical/Transport Layer
Control Capture CSRs. User logic must provide the correct
capture information on the appropriate input signals when
assserting the long_data_streaming_segment_set
input port.
1'b0
SHRT_DATA_STRM_SGMNT_EN [18] RW
Enable reporting of a non-final data streaming segment with
a payload size less than the MTU. Save and lock capture
information in the appropriate Logical/Transport Layer
Control Capture CSRs. User logic must provide the correct
capture information on the appropriate input signals when
assserting the short_data_streaming_segment_set
input port.
1'b0
DS_PDU_LEN_ERR_EN [17] RW
Enable reporting of a reassembled PDU that differs from the
PDU length specified in the end data streaming segment
packet header. Save and lock capture information in the
appropriate Logical/Transport Layer Control Capture CSRs.
User logic must provide the correct capture information on
the appropriate input signals when assserting the
data_streaming_pdu_length_error_set
input port.
