A logic circit external to a microprocessor monitors selected processor I/O pins to determine the current processor cycle and, in response to a hold request signal, drives the processor into a hold state at the appropriate time in the cycle. The logic circuit also includes a "lockbus" feature that, when the processor is not idle, "locks" the microprocessor to the local CPU bus for a predetermined period of time immediately after the processor is released from a hold state.
