    摘要: The central processing unit of an integrated circuit data processing system includes both means for processing a first non-maskable interrupt (NMI) request received by the data processing system on a first NMI request line and means for processing a second NMI request received by the data processing system on a second NMI request line different from the first NMI request line and within a predefined time period after receipt of the first NMI request. Both. NMI requests are serviced by the data processing system even if the second NMI request is received prior to completion of processing of the first request.
