A flexible interrupt module has its control registers in the I/O space with an additional global interrupt enable bit in the status

register. All the different interrupts have a separate interrupt vector in the interrupt vector table at the beginning of the

program memory. The different interrupts have priority in accordance with their interrupt vector position. The lower the

interrupt vector address, the higher the priority.
