Arithmetic Mode
The arithmetic mode is ideal for implementing adders, counters,
accumulators, and comparators. An LE in arithmetic mode implements a
2-bit full adder and basic carry chain (see
mode can drive out registered and unregistered versions of the LUT
output. Register feedback and register packing are supported when LEs
are used in arithmetic mode.
