Abstract
A microprocessor system works in conjunction with an application dependent logic module tailored to serve the particular requirements of a given peripheral device. The microprocessor is provided with a linear microsequencer circuit to operate with all types of application dependent logic modules and to provide instructions and control for data transfer operations. Means are provided in the microprocessor for operation in a 'normal' mode whereby a first set of accumulator registers and flag registers are used exclusively, and in a 'background' or interrupt mode where a second set of accumulator registers and flag registers are used exclusively.
