Figure 2–5. Cyclone LE
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 internal logic can drive the register's
clock and clear control signals. Either general-purpose I/O pins or
internal logic 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 combinatorial 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 direct link
routing connections and one drives local interconnect resources. This
allows the LUT to drive one output while the register drives another
output. This feature, called register packing, improves device utilization
because the device can use the register and the LUT for unrelated
