WebINTR is an input to the 8086 that can be used by an external device to signal that it need to be serviced. Logic 1 at INTR represents an active interrupt request. When an interrupt request has been recognized by the 8086, it indicates this fact to external circuit with pulse to logic 0 at the INTA output. WebFeb 21, 2024 · Once the NMI pin goes high, the interrupt is scheduled, even if the pin goes low. For a regular interrupt, the INTR pin must be high at the start of an instruction. Thus, NMI is latched but INTR is not. ↩. Since the 8086 has multiple interrupt sources, you might wonder how multiple interrupts are handled at the same time.

WebIf that IR input of the master is unmasked and if that input is a higher priority than any other IR inputs currently being serviced, then the master will send an INT signal to the 8086 INTR input. If the INTR interrupt is enabled, the 8086 will go through its INTR interrupt procedure and sends out two INTA pulses to both the master and the slave. WebInterrupt Priority in 8086: As far as the Interrupt Priority in 8086 are concerned, software interrupts (All interrupts except single step, NMI and INTR interrupts) have the highest priority, followed by NMI followed by INTR.
