28.1.3 Logic Function

There are eight available logic functions including:

  • AND-OR
  • OR-XOR
  • AND
  • SR Latch
  • D Flip-Flop with Set and Reset
  • D Flip-Flop with Reset
  • J-K Flip-Flop with Reset
  • Transparent Latch with Set and Reset

Logic functions are shown in the following diagram. Each logic function has four inputs and one output. The four inputs are the four data gate outputs of the previous stage. The output is fed to the inversion stage and from there to other peripherals, an output pin, and back to the CLC itself.
