Abstract: the Real mode interrupt vector table (IVT), but it may be desirable to redirect interrupts for certain vectors to the Protected mode interrupt descriptor table (IDT). The processor's Virtual-8086 mode , interrupt vector table (IVT). If VIF has been cleared, the operating system holds the interrupt pending , normally, vectoring directly to a Virtual-8086 service routine via the Virtual-8086 interrupt vector , Instructions that Modify the IF or VIF Flags-Virtual-8086 Mode Interrupt Extensions (VME) . . . . . . . . .

Abstract: interrupt is presented to the CPU. 6-4 The ISCC can return an interrupt vector that encodes with the , but not return an interrupt vector [note that the no vector bit(s) in the SCC section (WR9 bit 1) and in the DMA section (ICR bit 5) individually control whether or not an interrupt vector returns by these cores]. The interrupt vector can program to include a status field showing the internal ISCC source of the interrupt. During the interrupt acknowledge cycle, the ISCC returns the interrupt vector -

Abstract: bus. The ISCC can return an Interrupt vector that encodes with the type of interrupt pending , ) individually control whether or not an interrupt vector returns by these cores]. The interrupt vector can , (whether single or double). INTACK is the strobe for the interrupt vector. Thus when INTACK goes active, the ISCC drives the bus and presents the interrupt vector to the CPU. When the status acknowledge type programs, the ISCC drives the bgs with the interrupt vector when RD or DS are active. WAITRDY programs to -
