Abstract

A dual latch character pacing circuit on a semiconductor chip controls data transfer between a pair of microprocessor which have significantly different data transfer rates. A first and second latch are connected in a parallel data path between the two microprocessor. The timing circuit includes a flip-flop which clocks the data between the latches. A one-shot timer is re-started on each transfer of data thereby insuring that the rate of transfer is substantially constant over a character period.
