As mentioned earlier, an additional output (MC31) and a dedicated connection between
shift registers allows connecting the last bit of one shift register to the first bit of the next,
without using the LUT O6 output. Longer shift registers can be built with dynamic access
to any bit in the chain. The shift register chaining and the F7AMUX, F7BMUX, and F8MUX
multiplexers allow up to a 128-bit shift register with addressable access to be implemented
in one SLICEM.
