Read Data, Write Data, and Lock Packets
In addition to the general packet display elements listed on page 50, the following
information may be found in the display for read, write, and lock packets:
• Transaction labels (lbl) — This value is taken from the packet’s tl field. The label is dis-
played in the bottom half of the field that contains the transaction code.
• Destination_IDs (dest_ID) — The value of the packet’s destination_ID field.
• Source_IDs (src_ID) — The value of the packet’s source_ID field.
• Retry Codes (rt) — The value of the packet’s rt field.
• Response code (rcode) — The packet’s rcode field value.
• Destination_offsets (dest_offset) — The value of the packet’s destination_offset field.
Not present in response packets.
• Data length (data_len) — The value of the packet’s data_length field.
• Extended Tcodes (ext_tcode) — The value of the packet’s extended_tcode field.
• Quadlet data (quadlet_data) — The value of the packet’s quadlet_data field.
• Header CRCs (header_CRC) — The value of the packet’s header_CRC field.
• Data (Data) — The Data field can be expanded and collapsed. By default, it is collapsed,
and the value shown is the number of quadlets contained in the packet’s data block
field. When expanded, the actual quadlet data from the data block field is shown.
• Acknowledge packet (ACK) codes — The value of the ACK code that was sent in
response to the packet.
• User Data — The value in this field represents the state of the breakout board signals.
Present only when the option “Save External Interface Signals” is selected on the Gen-

• Argument value (arg_value) — The value of the packet’s arg_value field.
• Data value (data_value) — The value of the packet’s data_value field.
• Data CRC (data_CRC) — The value of the packet’s data_CRC field.
• Old value (old_value) — The value of the packet’s old_value field.
• Idle times (Idle) — The Idle field displays the time between the end of the packet and the
beginning of the next packet.
