Question: 1. The 68000 interrupt structure requires several external packages, if its full facilities are to be used. Suppose that only four interrupt levels are needed (IRQ4*-IRQ7*). Design a minimum component circuit that is able to support four levels of vectored interrupt. Hint: Think PROM.

2. A 68000-based microcomputer has the requirement that an interrupt be generated at least every T seconds. Design a circuit to generate an interrupt on IRQ1* every T seconds, provided that interrupts IRQ2*-IRQ7* have not been asserted during the previous T seconds.
