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
FFFC00
H
and FFFFFF
H
as shown in Table 3.2-1 .
