Flag in microprocessor
WebThe 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 … WebClear Carry Flag: This instruction resets the carry flag CF to 0. CLD: Clear Direction Flag: This instruction resets the direction flag DF to 0. CLI: Clear Interrupt Flag: This instruction resets the interrupt flag IF to 0. CMC: This instruction take complement of carry flag CF. STC: Set carry flag CF to 1. STD: Set direction flag to 1. STI ...
