Step 1:
Isochronous header quadlet is loaded into header0 register at 38h through a write
operation from the microcontroller interface.
Step 2:
Header quadlet is forwarded to the transmitter of the link core.
Step 3:
Packet data (payload only) is transmitted through the data mover directly to the transmitter
of the link core.
Step 4:
Isochronous packet is sent to the 1394 bus through the Phy.
NOTE:
The data coming through the data mover port is typically supplied by an external
fast memory block (i.e., FIFO, DRAM). This external memory logic may begin
transmitting data through to the data mover port exactly one DMCLK cycle after the
DMPRE output pin on the GP2Lynx is asserted high.
5.1.2.2
Isochronous Packet Transmit Without Automatic Header Insertion
In this mode, the packet header and data information is loaded through the data mover port. This mode is
sometimes called isochronous packet transmit with manual header insertion. This is because the header
quadlet is not preloaded into the header0 register via the microcontroller interface. Instead, it is inserted
manually
into the data stream at the same time as the rest of the packet. The following steps further illustrate
the process:
Step 1:
Isochronous header information (only one header quadlet in this case) is fetched into the
header0 register at 38h through the data mover port.
Step 2:
Header quadlet is forwarded to the transmitter of the link core.
Step 3:
Packet data (payload only) is transmitted through the data mover directly to the transmitter
of the link core.
Step 4:
Isochronous packet is sent to the 1394 bus through the Phy.
