1. Write the C statement needed to arm the Port J interrupt?
2. What does placing asm("cli") at the beginning of an ISR do?
3. Explain what the software interrupt (SWI) does.
4. ROM Vector table addresses $FFD2 belongs to which interrupt.
5. Can an interrupt be interrupted as it is being processed? If so, is there a way to stop that from happening? If not, when does a second, pending interrupt start getting serviced?
6. What happens if interrupt request come in both IRQ~ and XIRQ~ at the same time? Assume both are enabled and have their own ISRs.
