ILL_TRAN_TARGET

[26]

RO

(1)

Received a packet that contained a destination ID that is not
defined for this end point. Set when the RapidIO II IP core
detects this situation or when the
illegal_transaction_target_error_set

input signal

changes value from 0 to 1.

An endpoint with multiple ports and a built-in switch function
might not report this situation as an error.

1'b0

MSG_REQ_TIMEOUT

(2)

[25]

RO

(1)

A required message request has not been received within the
specified time-out interval. Set when the
message_request_timeout_set

input signal changes value

from 0 to 1.

1'b0

PKT_RSP_TIMEOUT

(2)

[24]

RO

(1)

A required response has not been received within the specified
time-out interval. Set when the RapidIO II IP core detects this
situation or when the slave_packet_response_timeout_set
input signal changes value from 0 to 1.

1'b0

UNSOLICIT_RSP

[23]

RO

(1)

Received an unsolicited or unexpected response packet (I/O,
message, or GSM logical for endpoints; Maintenance for
switches). Set when the RapidIO II IP core detects this situation
or when the unsolicited_response_set input signal
changes value from 0 to 1.

1'b0

UNSUPPORT_TRAN

[22]

RO

(1)

Received a transaction that is not supported in the Destination
Operations CAR. Set when the RapidIO II IP core detects this
situation or when the unsupported_transaction_set input
signal changes value from 0 to 1.

MISSING_DATA_STRM_

CNTXT

(2)

[21]

RO

(1)

Received a continuation or end data streaming segment for a
closed or non-existent segmentation context. Set when the
missing_data_streaming_context_set

input signal

changes value from 0 to 1.

1'b0

OPEN_EXSTG_DATA_STRM_

CNTXT

(2)

[20]

RO

(1)

Received an initial or single data streaming segment for an
already-open segmentation context. Set when the
open_existing_data_streaming_context_set

input signal

changes value from 0 to 1.

1'b0

LONG_DATA_STRM_SGMNT

(2)

[19]

RO

(1)

Received a data streaming segment with a payload size greater
than the MTU. Set when the
long_data_streaming_segment_set

input signal changes

value from 0 to 1.

1'b0

SHRT_DATA_STRM_SGMNT

(2)

[18]

RO

(1)

Received a non-final data streaming segment with a payload size
less than the MTU. Set when the

input signal changes

value from 0 to 1.

1'b0

DS_PDU_LEN_ERR

(2)

[17]

RO

(1)

The length of a reassembled PDU differs from the PDU length
specified in the end data streaming segment packet header. Set
when the data_streaming_pdu_length_error_set input
signal changes value from 0 to 1.
