ABSTRACT:
A microprocessor system includes a microprocessor, a memory, and an interface adaptor all coupled to a data bus. The interface adaptor is coupled between the data bus and a peripheral device, such as a teleprinter. A first interrupt conductor is connected to the peripheral device and to interrupt logic circuitry in the interface adaptor. A second interrupt conductor is connected to the microprocessor and the interrupt logic circuitry. The interrupt logic circuitry is also coupled to and interrogatable by the microprocessor via the data bus. The interrupt logic circuitry stores interrupt contrl information from the data bus, and generates a second interrupt signal on the second interrupt conductor in response to the stored interrupt control information and an interrupt signal generated on the first interrupt conductor by the peripheral device. The interrupt logic circuitry also stores status information indicative of the occurrence of the first interrupt signal and effects interrogation of that status via the data bus.
