Universal programmable counter/timer and address register module

Abstract From the Canadian patent

A programmable apparatus for use as an accumulator a, time base generator or a memory address register. A clock input receives a clock input signal. A computer input which, may include a bidirectional data bus receives inputs from a, computer. A processor processes at least one of the clock input signal and the input from the computer to produce at least one output. A control circuit controls the processor in accordance with further input. from the computer to determine the output produced. An output selector which may in-, clude a multiplexer for directly addressing memory selects, at least one output to be used externally of the apparatus.
