PRELIMINARY
7.3 3-Bit LUT or D Flip Flop with Set/Reset Macrocells
There are six macrocells that can serve as either 3-bit LUTs or as D Flip Flops with Set/Reset inputs. When used to implement
LUT functions, the 3-bit LUTs each take in three input signals from the connection matrix and produce a single output, which goes
back into the connection matrix. When used to implement D Flip Flop function, the three input signals from the connection matrix
go to the data (D) and clock (CLK) and Set/Reset (nRST/nSET) inputs for the Flip Flop, with the output going back to the
connection matrix.
DFF3 operation is described below:
• If reg <1237> = 0, and the CLK is rising edge triggered, then Q=D, otherwise Q will not change
If reg <1237> = 1, then data from D is written into the DFF by the rising edge on CLK and output to Q by the falling edge on CLK.
