Interrupt Vector - Fujitsu MB90390 Series Hardware Manual

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 " and "FFFFFF
