If the seven-input function is un-registered, the unused eighth input is available for register packing. The second
register, reg1, is not available.

Arithmetic Mode
The arithmetic mode is ideal for implementing adders, counters,
accumulators, wide parity functions, and comparators. An ALM in
arithmetic mode uses two sets of two four-input LUTs along with two
dedicated full adders. The dedicated adders allow the LUTs to be
available to perform pre-adder logic; therefore, each adder can add the
output of two four-input functions. The four LUTs share the dataa and
datab inputs. As shown in
adder0, and the carry-out from adder0 feeds to carry-in of adder1. The
carry-out from adder1 drives to adder0 of the next ALM in the LAB.
ALMs in arithmetic mode can drive out registered and/or un-registered
versions of the adder outputs.
