Link Packet Data Formats
The data formats for transmission and reception of data are shown below. The transmit format describes the expected organization for data
presented to the link at the asynchronous transmit, physical response, or isochronous transmit FIFO interfaces.
12.5.1
Asynchronous Transmit Packet Formats
These sections describe the formats in which packets need to be delivered to the queues (FIFOs) for transmission. There are four basic formats
as follows:
ITEM
FORMAT
USAGE
TRANSACTION CODE
(tCode)
1
No packet data
Quadlet read requests
4

No-packet data
Quadlet/block write responses
2

3

9

Unformatted transmit
Concatenated self-ID / PHY packets
Ehex
Each packet format uses several fields (see names and descriptions below). More information about these fields (not the format) can be found
in the 1394 specification. Grey fields are reserved and should be set to zero values.
12.5.1.1
No-data Transmit
The no-data transmit formats are shown in Figures 6 and 7. 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).
