Each LE’s programmable register can be configured for D, T, JK, or SR
operation. Each register has data, clock, clock enable, and clear inputs.
Signals that use the global clock network, 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. 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 direct link
routing connections and one drives local interconnect resources, allowing
the LUT to drive one output while the register drives another output. This
feature, register packing, improves device utilization because the device
can use the register and the LUT for unrelated functions. When using
register packing, the LAB-wide synchronous load control signal is not
available. See
