No-Data Transmit Format
Field Name
Description
spd
This field indicates the speed at which this packet is to be sent. 00=100 Mbs, 01=200 Mbs, and 10=400 Mbs.
11 = undefined
tLabel
This field is the transaction label, which is used to pair up a response packet with its corresponding request packet.
rt
The retry code for this packet. Supported values are: 00=retry1, and 01=retryX.
tCode
The transaction code for this packet.
DestinationID
Contains a node ID value.
DestinationOffsetHigh
DestinationOffsetLow
The concatenation of these two field addresses a quadlet in the destination node’s address space.
rCode
Response code for write response packet.
rCode
Meaning
0
Node successfully completed requested operation.
1–3
Reserved
4
Resource conflict detected by responding agent. Request may be retried.
5
Hardware error. Data not available.
6
Field within request packet header contains unsupported or invalid value.
7
Address location within specified node not accessible.
8–Fh
Reserved

Quadlet Transmit
Three quadlet transmit formats are shown below. In these figures: The first quadlet contains packet control information. The second and third
quadlets contain 16-bit destination ID and either the 48-bit quadlet-aligned destination offset (for requests) or the response code (for responses).
The fourth quadlet contains the quadlet data for read response and write quadlet request formats, or the upper 16 bits contain the data length
for the block read request format.
