In a multimicroprocessor system, where one or more of the microprocessors (MPUs) are provided with and utilize on-chip microcode, it is possible and advantageous to bypass faulty microcode until a permanent fix therefore is implemented. Such a capability is particularly useful in a microprocessor system that is utilizing microcoded MPUs to emulate a main frame instruction set.
