Hardware interrupts: If the signal for the processor is from external device or hardware is called hardware interrupts. Hardware interrupts are used by the devices to communicate that they require attention from the OS. Hardware interrupts are implemented by using electrical signals that are sent to the processor from an external device, which can be the …

WebThe first and last lines of this function are assembly language instructions that disable/enable interrupt handling. The first instruction (asm(" sei")) sets the I bit in the condition code register, thereby disabling any interrupts. This prevents us from catching an interrupt while we're trying to initialize the system.
