3. Transmit Data Path
The DM isochronous transmit reads data from the DM interface (DMD[0
15] lines) and passes it to the 1394
isochronous transmit interface in accordance with Figure 5
2. The data path is shown in Figure 5
3. The
asynchronous header registers will contain the latest extracted header from the asynchronous stream when
the header is supplied via the DM port. For automatic header insertion, the
datalength
field in the header
register will be automatically updated by the payload size of the previous asynchronous transmit packet.
This option can be turned off by setting the appropriate bits in the DM control registers. The DM
asynchronous transmit reads data from the DM interface (DMD[0:15] lines) and passes it to the 1394
asynchronous interface in accordance with Figure 5
