Virtex-5 FPGA Integrated Endpoint Block Interface Descriptions
R
After transmission of a packet, a subsequent packet on the same channel (FIFO and TC)
can be sent immediately. For packets on a different channel (FIFO or TC), the user logic
must pause until
LLKTXDSTRDYN is asserted for two cycles after LLKTXEOFN before
changing the
LLKTXCHFIFO or LLKTXCHTC signal.
If the transmit buffer becomes full during packet transfer, it deasserts
LLKTXDSTRDYN and
stalls data transfers on the Transaction Layer interface until space becomes available again
as the packet is sent over the serial interface. The user can optionally check the amount of
space in a channel using
LLKTXCHANSPACE and decide to not begin sending the packet
over the Transaction Layer interface if insufficient space is available to send the packet
without stalling. The requirement on channel switching timing as shown in Figure 2-6
must also be observed.
LLKTXENABLEN is ignored unless LLKTXSRCRDYN and LLKTXDSTRDYN are asserted.
Receive
The receive portion of the interface passes the data received from the link partner to the
user application in fabric.
