ADVANCE INFORMATION
When used to implement LUT functions, the 3-bit LUTs each take in three input signals from the connection mux and produce a single output, which goes back into the connection mux. These LUTs can be configured to any 3-input user defined function, including the following standard digital logic functions (AND, NAND, OR, NOR, XOR, XNOR).
When programmed for a LUT function, each macro-cell uses an 8-bit register to define their output function.
Table 7-17 shows truth tables for the 3-bit LUT.
