Each LE’s programmable register can be configured for D, T, JK, or SR operation. Each
register has data, true asynchronous load data, clock, clock enable, clear, and
asynchronous load/preset inputs. Global signals, general-purpose I/O pins, or any
LE can drive the register’s clock and clear control signals. Either general-purpose I/O
pins or LEs can drive the clock enable, preset, asynchronous load, and asynchronous
data. The asynchronous load data input comes from the data3 input of the LE. For
combinational functions, the LUT output bypasses the register and drives directly to
the LE outputs.
Each LE has three outputs that drive the local, row, and column routing resources. The
LUT or register output can drive these three outputs independently. Two LE outputs
drive column or row and DirectLink routing connections and one drives local
interconnect resources. This allows the LUT to drive one output while the register
drives another output. This register packing feature improves device utilization
because the device can use the register and the LUT for unrelated functions. Another
special packing mode allows the register output to feed back into the LUT of the same
LE so that the register is packed with its own fan-out LUT. This provides another
mechanism for improved fitting. The LE can also drive out registered and
unregistered versions of the LUT output.
