operation, which consists of activating
RENandenablingarisingRCLKedge,
will shift the word from internal memory to the data output lines.
In FWFT mode, the first word written to an empty FIFO is clocked directly
to the data output lines after three transitions of the RCLK signal. A
RENdoes
not have to be asserted for accessing the first word. However, subsequent
words written to the FIFO do require a LOW on
REN for access. The state of
the FWFT/SI input during Master Reset determines the timing mode in use.
For applications requiring more data storage capacity than a single FIFO
canprovide,theFWFTtimingmodepermitsdepthexpansionbychainingFIFOs
in series (i.e. the data outputs of one FIFO are connected to the corresponding
data inputs of the next). No external logic is required.
These FIFOs have five flag pins,
EF/OR (Empty Flag or Output Ready),
FF/IR (Full Flag or Input Ready), HF (Half-full Flag), PAE (Programmable
Almost-Emptyflag)and
PAF(ProgrammableAlmost-Fullflag). TheEFandFF
functions are selected in IDT Standard mode. The
IR and OR functions are
selected in FWFT mode.
HF, PAE and PAF are always available for use,
irrespective of timing mode.
PAE and PAFcanbeprogrammedindependentlytoswitchatanypointin
memory. Programmableoffsetsdeterminetheflagswitchingthresholdandcan
beloadedbytwomethods:parallelorserial. Eightdefaultoffsetsettingsarealso
provided, so that
PAEcanbesettoswitchatapredefinednumberoflocations
from the empty boundary and the
PAF threshold can also be set at similar
predefinedvaluesfromthefullboundary. Thedefaultoffsetvaluesaresetduring
Master Reset by the state of the FSEL0, FSEL1, and
LD pins.
For serial programming,
SEN together with LD on each rising edge of
WCLK,areusedtoloadtheoffsetregistersviatheSerialInput(SI). Forparallel
programming,
WENtogetherwith LD oneachrisingedgeofWCLK,areused
to load the offset registers via Dn.
REN together with LD on each rising edge
ofRCLKcanbeusedtoreadtheoffsetsinparallelfromQnregardlessofwhether
serial or parallel offset loading has been selected.
During Master Reset (
MRS)thefollowingeventsoccur: thereadandwrite
pointers are set to the first location of the FIFO. The FWFT pin selects IDT
Standard mode or FWFT mode.
The Partial Reset (
PRS) also sets the read and write pointers to the first
location of the memory. However, the timing mode, programmable flag
programmingmethod,anddefaultorprogrammedoffsetsettingsexistingbefore
PartialResetremainunchanged.Theflagsareupdatedaccordingtothetiming

when reprogramming programmable flags would be undesirable.
Itisalsopossibletoselectthetimingmodeofthe
PAE(ProgrammableAlmost-
Empty flag) and
PAF (Programmable Almost-Full flag) outputs. The timing
modes can be set to be either asynchronous or synchronous for the
PAE and
PAFflags.
