When
EF goes HIGH, Retransmit setup is complete and read operations
may begin starting with the first location in memory. Since IDT Standard
mode is selected, every word read including the first word following
Retransmit setup requires a LOW on
RENtoenabletherisingedgeofRCLK.
SeeFigure11,RetransmitTiming(IDTStandardMode),fortherelevanttiming
diagram.
If FWFT mode is selected, the FIFO will mark the beginning of the
Retransmit setup by setting
OR HIGH. During this period, the internal read
pointer is set to the first location of the RAM array.
When
OR goes LOW, Retransmit setup is complete; at the same time,
the contents of the first location appear on the outputs. Since FWFT mode
isselected,thefirstwordappearsontheoutputs,noLOWon
RENisnecessary.

of RCLK. See Figure 12, Retransmit Timing (FWFT Mode), for the relevant
timingdiagram.
For either IDT Standard mode or FWFT mode, updating of the
PAE, HF
and
PAF flags begin with the rising edge of RCLK that RT is setup. PAE is
synchronized to RCLK, thus on the second rising edge of RCLK after
RT is
setup, the
PAE flag will be updated. HF is asynchronous, thus the rising
edge of RCLK that
RT is setup will update HF. PAF is synchronized to
WCLK, thus the second rising edge of WCLK that occurs tSKEW after the
rising edge of RCLK that
RT is setup will update PAF. RT is synchronized
to RCLK.
