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 pro-
gram memory. The different interrupts have priority in accordance with their interrupt vector position. The lower the
interrupt vector address the higher the priority.
