WebNote The interrupt processing must remove the cause of the interrupt or the above sequence will loop indefinitely. It is usual in simple interrupt processing to disable the interrupts at the computer end during interrupt "servicing" to prevent recursion. Because of the machine specific nature of interrupts, high-level support is a bit difficult. 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.
