Similar to the carry chains, the top and bottom halves of shared arithmetic chains in
alternate LAB columns can be bypassed. This capability allows the shared arithmetic
chain to cascade through half of the ALMs in an LAB while leaving the other half
available for narrower fan-in functionality. Every other LAB column is top-half
by-passable, while the other LAB columns are bottom-half by-passable.

LUT-Register Mode
LUT-register mode allows third-register capability within an ALM. Two internal
feedback loops allow combinational ALUT1 to implement the master latch and
combinational ALUT0 to implement the slave latch needed for the third register. The
LUT register shares its clock, clock enable, and asynchronous clear sources with the
top dedicated register.
