3.3
Access to all the transmit FIFOs is fundamentally the same; only the address to where the write is made
changes.
FIFO Access
3.3.1
The TSB12LV01A controller FIFO-access address map shown in Figure 3–3 illustrates how the FIFOs are
mapped. The suffix _First denotes a write to the FIFO location where the first quadlet of a packet should
be written when the writer wants to transmit the packet. The first quadlet is held in the FIFO until a quadlet
is written to an update location.
General
The suffix _Continue denotes a write to the FIFO location where the second through n–1 quadlets of a packet
should be written.
The second through n–1 quadlets are held in the FIFO until a quadlet is written to an update location.
The suffix Continue & Update denotes a write to the FIFO location where the last quadlet of a multiple quadlet
packet should be written. Another method allows the second through n quadlets of a packet to be written
to an address with this suffix when the writer wants the packet to be transmitted as soon as possible.
However, in this case the writes to the FIFO must be put into the FIFO faster than data is removed from the
FIFO and placed on the 1394 bus or an error will result.
