Webdisables (if cleared) all interrupts. Individual interrupts can be disabled through their correspond-ing enable bits in the INTCON register. The GIE bit is cleared on reset. The “return from interrupt” instruction, RETFIE, exits the interrupt routine as well as sets the GIE bit, which allows any pending interrupt to execute. WebPVI mode (protected-mode virtual interrupts): CR0.PE = 1, EFLAGS.VM = 0, CPL = 3, and CR4.PVI = 1; VME mode (virtual-8086 mode extensions): CR0.PE = 1, EFLAGS.VM = 1, and … WebINT 3. The INT 3 instruction is defined for use by debuggers to temporarily replace an instruction in a running program, in order to set a breakpoint. Other INT instructions are encoded using two bytes.
