An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

The Interrupt flag (IF) is a flag bit in the CPU's FLAGS register, which determines whether or not the (CPU) will respond immediately to maskable hardware interrupts. If the flag is set to 1 maskable interrupts are enabled. If reset (set to 0) such interrupts will be disabled until interrupts are enabled. The Interrupt flag does not affect the handling of non-maskable interrupts (NMIs) or software interrupts generated by the INT instruction.

Property Value
dbo:abstract
  • The Interrupt flag (IF) is a flag bit in the CPU's FLAGS register, which determines whether or not the (CPU) will respond immediately to maskable hardware interrupts. If the flag is set to 1 maskable interrupts are enabled. If reset (set to 0) such interrupts will be disabled until interrupts are enabled. The Interrupt flag does not affect the handling of non-maskable interrupts (NMIs) or software interrupts generated by the INT instruction. (en)
  • В системе команд x86 совместимых процессоров инструкция CLI — сокращение от «Clear Interrupt-Enable Flag». Она сбрасывает interrupt flag (IF) в регистре EFLAGS. Когда этот флаг сброшен процессор игнорирует все прерывания (кроме NMI) от внешних устройств. Опкод данной инструкции — 0xFA. (ru)
