Abstract
A digital control system for an internal combustion engine uses a two stage register. The register is used to store digital data representative of sensed engine operating conditions and to feed such data to a programmable digital computer for processing. Processing time is improved by reading only one register containing the most significant data bits of the stored data for engine parameters having a relatively narrow dynamic range and reading both registers, containing all data bits of the stored data for engine parameters having a relatively large dynamic range.
