The following table provides the Slave FIFO Synchronous Packet End Strobe Parameters with Externally Sourced IFCLK.

There is no specific timing requirement that needs to be met for
asserting the PKTEND pin concerning asserting SLWR.
PKTEND is asserted with the last data value clocked into the
FIFOs or thereafter. The only consideration is that the set up time

Although there are no specific timing requirements for asserting
PKTEND in relation to SLWR, there exists a specific case
condition that needs attention. When using the PKTEND to
commit a one byte or word packet, an additional timing
requirement must be met when the FIFO is configured to operate
in auto mode and it is necessary to send two packets back to

In this particular scenario, the developer must assert the
PKTEND at least one clock cycle after the rising edge that
caused the last byte or word to be clocked into the previous auto
committed packet.

number of bytes in the FIFO reaches X (value set in AUTOINLEN
register) and the second one byte or word short packet being
committed manually using PKTEND. Note that there is at least
one IFCLK cycle timing between asserting PKTEND and
clocking of the last byte of the previous packet (causing the
packet to be committed automatically). Failing to adhere to this
timing results in the FX2 failing to send the one byte or word short
packet.
