When used to implement LUT functions, the 4-bit LUT takes in four input signals from the connection matrix and produces a single output, which goes back into the connection matrix. When used to implement 8-Bit Counter / Delay function, two of the four input signals from the connection matrix go to the clock (CLK) and reset (DLY_IN/Reset_IN) inputs for the counter/delay, with the output going back to the connection matrix. This macrocell has an optional Finale State Machine (FSM) function. It has two additional matrix inputs for Up and Keep to support FSM functionality. The counter is counting down by deafault. Logic 1 on input Up reverses counting. Logic 1 on input Keep pauses counting.
