An additional 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 D-output (see
Figure
The shift register chaining and the MUXF5, and MUXF6 multiplexers allow up to a 64-bit
shift register with addressable access to be implemented in one CLB.
