ABSTRACT:
In an automotive engine control microcomputer the frequency of interrupt programs initiated by a pulse from an engine speed tachogenerator is prevented from being excessive as a result of loose connections or other malfunctions or distrubances by blocking the access of tachogenerator pulses to the interrupt port of the microcomputer for a predetermined interval following a successful interrupt from that source. If another signal that would produce an interrupt from that source is received during that interval, a circumstance indicative of probable malfunction, the blocking of interrupts from that source is continued for another interval of the same length.
