the
LD (Load) pin. During Master Reset, the state of the LD input determines
whether serial or parallel flag offset programming is enabled. A HIGH on
LD
duringMasterResetselectsserialloadingofoffsetvalues. ALOWon
LDduring
Master Reset selects parallel loading of offset values.
In addition to loading offset values into the FIFO, it is also possible to read
the current offset values. Offset values can be read via the parallel output port
Q0-Qn, regardless of the programming mode selected (serial or parallel). It is
not possible to read the offset values in serial fashion.
Figure 3, Programmable Flag Offset Programming Sequence, summaries
thecontrolpinsandsequenceforbothserialandparallelprogrammingmodes.
For a more detailed description, see discussion that follows.

Master Reset, regardless of whether serial or parallel programming has been
selected. Valid programming ranges are from 0 to D-1.
SYNCHRONOUS vs ASYNCHRONOUS PROGRAMMABLE FLAG TIM-
ING SELECTION
The IDT72V36100/72V36110 can be configured during the Master Reset
cycle with either synchronous or asynchronous timing for
PAFandPAEflags
by use of the PFM pin.
If synchronous
PAF/PAE configuration is selected (PFM, HIGH during
MRS), the PAF is asserted and updated on the rising edge of WCLK only and
not RCLK. Similarly,
PAEisassertedandupdatedontherisingedgeofRCLK
only and not WCLK. For detail timing diagrams, see Figure 17 for synchronous
PAF timing and Figure 18 for synchronous PAE timing.
If asynchronous

MRS),thePAFisassertedLOWontheLOW-to-HIGHtransitionofWCLKand

NOTES:
1. n = empty offset for
PAE.
2. m = full offset for
PAF.
3. As well as selecting serial programming mode, one of the default values will also
be loaded depending on the state of FSEL0 & FSEL1.
4. As well as selecting parallel programming mode, one of the default values will
also be loaded depending on the state of FSEL0 & FSEL1.
