ABSTRACT:
A resettable electronic counter employing an integrated solid state calculator circuit element, or chip, includes counter reset circuitry for automatically resetting the counter. The calculator circuit provides timing signals and is responsive to timing signals selectively connected to an arithmetic and control section thereof for clearing a count stored in registers thereof and display means external thereto, for storing a selected count in the registers, and for cumulatively adding indexing signals to the stored count. The counter reset circuitry includes control logic and a sequence counter actuated by a reset signal to generate a series of step signals. The step signals and certain timing signals are connected to the control logic which is in turn connected to the arithmetic and control section of the calculator circuit. The reset circuitry is operable to apply, to the arithmetic and control section, in predetermined sequence, those timing signals for clearing and for storing a count, and additionally to control the application of count indexing signals.
