CHAPTER 3 INTERRUPTS

3.2 Interrupt Vector

An interrupt vector uses the same area for both hardware and software interrupts. For

example, interrupt request number INT42 is used for a delayed hardware interrupt and

for software interrupt INT #42. Therefore, the delayed interrupt and INT #42 call the

same interrupt processing routine. Interrupt vectors are allocated between addresses

FFFC00H and FFFFFFH as shown in Table 3.2-1 .
