Abstract: Virtual-8086 interrupt vector table (IVT) at address 0 of the task address space. However, it may still be , Virtual-8086 mode, software interrupts (those caused by INTn instructions that vector through interrupt gates , interrupts. Software interrupts in Virtual-8086 mode are normally directed to the Real mode interrupt vector , interrupt descriptor table (IDT). The processor's Virtual-8086 mode extensions support both of these , system permits access to the appropriate Virtual8086 handler via the interrupt vector table (IVT). If VIF ... Original

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 ...

The interrupt vector can program to , 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 ... OCR Scan
