8 / 115 page Lattice Semiconductor ispXPGA Family Data Sheet 8 Figure 6. ispXPGA Wide Logic Generator Configurable Sequential Element There are two registers in each CSE for a total of eight registers in each PFU. This high register count assists in implementing efficient pipelined applications with no utilization penalty. Each register can be configured as a latch or D type flip-flop with either synchronous or asynchronous set or reset. Figure 2 shows the signals that feed the register’s D inputs. Feed-through signals in the architecture ensure that registers are efficiently utilized even if the accompanying LUT is occupied. Control Logic The control signals available to the registers in a PFU are Clock, Clock Enable, and Set/Reset. Figure 7 shows the various options available to generate the clock signal. As can be seen, the clock signal is the output of a 12:1 MUX with true and compliment versions available from the 12:1 MUX. Each CSE can chose whether it uses the true or complement form of the clock. Figure 8 shows the Set/Reset selection for each PFU in the ispXPGA.
