PLC Latches/Flip-Flops
The eight general-purpose latches/FFs in the PFU can
be used in a variety of congurations. In some cases,
the conguration options apply to all eight latches/FFs in
the PFU and
some apply to the latches/FFs on a nib-
ble-wide basis where the ninth FF is considered inde-
pendently. For other options, each latch/FF is
independently programmable. In addition, the ninth FF
can be used for a variety of functions.
Table 7 summarizes these latch/FF options. The
latches/FFs can be congured as either positive- or
negative-level sensitive latches, or positive or negative
edge-triggered ip-ops (the ninth register can only be
FF). All latches/FFs in a given PFU share the same
clock, and the clock to these latches/FFs can be
inverted. The input into each latch/FF is from either the
corresponding LUT output (F[7:0]) or the direct data
input (DIN[7:0]). The latch/FF input can also be tied to
logic 1 or to logic 0, which is the default.
* Not available for FF[8].
The eight latches/FFs in a PFU share the clock (CLK)
and options for clock enable (CE), local set/reset (LSR),
and front-end data select (SEL) inputs. When CE is dis-
abled, each latch/FF retains its previous value when
clocked. The clock enable, LSR, and SEL inputs can be
inverted to be active-low.
The set/reset operation of the latch/FF is controlled by
two parameters: reset mode and set/reset value. When
the global set/reset (
GSRN) and local set/reset (LSR)
signals are not asserted, the latch/FF operates normally.
The reset mode is used to select a synchronous or
asynchronous LSR operation. If synchronous, LSR has
the option to be enabled only if clock enable (CE or
ASWE) is active or for LSR to have priority over the
clock enable input, thereby setting/resetting the FF inde-
pendent of the state of the clock enable. The clock
enable is supported on FFs, not latches. It is imple-
mented by using a 2-input multiplexer on the FF input,
with one input being the previous state of the FF and the
other input being the new data applied to the FF. The
select of this 2-input multiplexer is clock enable (CE or
ASWE), which selects either the new data or the previ-
ous state. When the clock enable is inactive, the FF out-
put does not change when the clock edge arrives.
