Abstract

There is disclosed herein an up/down counter with a programmable terminal count. The up/down counter has a two level input structure such that new terminal counts may be written into the up/down counter asynchronously without disturbing operations of the up/down counter. Although the invention is described in the bidirectional sense, certain of the features are also applicable to unidirectional counters.
