摘要：Microprocessor with registered clock counting for at a predetermined countproducing a command signal of adjustable shape, and a hierarchical interrupt system foruse 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 fordowncounting, a secondary count section that is fed by said command signal output forcounting 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 saidsecondary command signal executes serial shifting and outputs a shaped version of thesecondary command signal. The above counting means is also associated to aparametrizeable interrupt priority mechanism.
