Web• Interrupt Flag Clearing: When an interrupt occurs (an interrupt flag is raised), the ISR must clear the flag that caused the interrupt. Interrupt Mask: A control bit that stops (masks) interrupt requests from being acted upon by the CPU. The CPU will have instructions that can mask or unmask interrupts.
