10.1.9.1.3 Fast Balanced Counter

This counter is only available for the SX, SX-A and eX families. It takes advantage of the architectural features of these families, including flip-flops with built-in enable and more powerful combinatorial cells. Using these two features, it is possible to build a very fast and compact binary counter without using “look-ahead” carry circuitry. This counter should be preferred over all the others available for this family.
