Integrating Job Characteristics, Sociotechnical Systems and Reengineering: Presenting a Unified Approach to Work and Organization Design

A control interface for a liquid crystal display having more than 80 characters uses a pair of controller/driver devices each having inputs for eight data bits but being adaptable to operate with four data bits from a 4-bit microprocessor. A standard 8-bit microprocessor is used to control the controller/driver devices by connecting the four bits of a low data nibble of the microprocessor to the four high data bits of one controller/driver and four bits of a high data nibble of the microprocessor to the four high data bits of the other controller/driver. The control interface can interface to liquid crystal displays with less than 80 characters without microprocessor modification.
