85 / 172 page SLG46534_DS_107 Page 84 of 171 SLG46534 9.8.8 Difference in Counter Value for Counter, Delay, One-Shot and Frequency Detect Modes There is a difference in counter value for Counter and Delay/One-Shot/Frequency Detect modes. The counter value is shifted for two rising edges of the clock signal in Delay/One-Shot/Frequency Detect modes compared to Counter mode. See Figure 46. 9.9 2-bit LUT or Programmable Pattern Generator The SLG46534 has one combination function macrocell that can serve as a logic or timing function. This macrocell can serve as a Look Up Table (LUT), or Programmable Pattern Generator (PGEN). When used to implement LUT functions, the 2-bit LUT takes in two input signals from the connection matrix and produce a single output, which goes back into the connection matrix. When used as a LUT to implement combinatorial logic functions, the outputs of the LUTs can be configured to any user defined function, including the following standard digital logic devices (AND, NAND, OR, NOR, XOR, XNOR). The user can also define the combinatorial relationship between inputs and outputs to be any selectable function. When operating as a Programmable Pattern Generator, the output of the macrocell with clock out a sequence of two to sixteen bits that are user selectable in their bit values, and user selectable in the number of bits (up to sixteen) that are output before the pattern repeats. See figure Figure 48. Figure 46.
