FIELD NAME
DESCRIPTION
sourceID
This is the node ID of the sender of this packet.
destination OffsetHigh,
destination OffsetLow
The concatenation of these two fields addresses a quadlet in the destination nodes address
space. This address must be quadlet aligned (modulo 4). (The upper four bits of the
destination OffsetHigh field are used as the response code for lock-response packets, and
the remaining bits are reserved.)
quadlet data
For write requests and read responses, this field holds the transferred data. For write
responses and read requests, this field is not present.
4.1.4
The block-receive format is shown in Figure 4–4. The first quadlet read from the FIFO is the packet token
described in Section 3.3.4. The first 16 bits of the second quadlet contain the destination node and bus ID,
and the remaining 16 bits contain packet–control information. The first 16 bits of the third quadlet contain
the node and bus ID of the source, and the remaining 16 bits of the third quadlet and the entire fourth quadlet
contain the 48–bit, quadlet–aligned destination offset address. The first 16 bits of the fifth quadlet contain
the dataLength field. This is the number of bytes of data in the block data section of the packet. The
remaining 16 bits represent the extended_tCode field. (See Table 6–11 of the IEEE 1394–1995 standard
for more information on extended_tCodes.) The block data, if any, follows the extended_tCode.
