NOTES:
1. n = Empty Offset, Default Values: n = 127 when parallel offset loading is selected or n = 1,023 when serial offset loading is selected.
2. m = Full Offset, Default Values: m = 127 when parallel offset loading is selected or m = 1,023 when serial offset loading is selected.

PROGRAMMING FLAG OFFSETS
FullandEmptyFlagoffsetvaluesareuserprogrammable.TheIDT72V2101/
72V2111hasinternalregistersfortheseoffsets.Defaultsettingsarestatedinthe
footnotesofTable1andTable2.OffsetvaluescanbeprogrammedintotheFIFO
inoneoftwoways;serialorparallelloadingmethod.Theselectionoftheloading
method is done using the
LD(Load)pin.DuringMasterReset,thestateofthe
LD input determines whether serial or parallel flag offset programming is
enabled. A HIGH on
LD during Master Reset selects serial loading of offset
valuesandinaddition,setsadefault
PAEoffsetvalueof3FFH(athreshold1,023
words from the empty boundary), and a default
PAF offset value of 3FFH (a
threshold 1,023 words from the full boundary). A LOW on
LD during Master
Resetselectsparallelloadingofoffsetvalues,andinaddition,setsadefault
PAE
offset value of 07FH (a threshold 127 words from the empty boundary), and
a default
PAF offset value of 07FH (a threshold 127 words from the full
boundary). See Figure 3, Offset Register Location and Default Values.
In addition to loading offset values into the FIFO, it also possible to read the
current offset values. It is only possible to read offset values via parallel read.
Figure 4, Programmable Flag Offset Programming Sequence, summa-
rizes the control pins and sequence for both serial and parallel programming
modes. For a more detailed description, see discussion that follows.
The offset registers may be programmed (and reprogrammed) any time
after Master Reset, regardless of whether serial or parallel programming
has been selected.
