ABSTRACT:
Microprocessor with registered clock counting for at a predetermined count producing a command signal of adjustable shape, and a hierarchical interrupt system for use therewith.
A microprocessor comprises registered counting means that counts clock pulses. Upon attainment of a predetermined count it generates a command signal. Furthermore, it has a presettable input section that recurrently receives a variable preset count for downcounting, a secondary count section that is fed by said command signal output for counting successive command signals and under control of attainment of a predetermined count generates a secondary command signal on a secondary output. Next, a programmable registered pulse shaper mechanism under control of said secondary command signal executes serial shifting and outputs a shaped version of the secondary command signal. The above counting means is also associated to a parametrizeable interrupt priority mechanism.
