Interrupt Factor And Interrupt Vector - Fujitsu F2MC-16LX Hardware Manual

CHAPTER 3 INTERRUPT
3.2

Interrupt Factor and Interrupt Vector

2
The F MC-16LX has functions corresponding to 256 types of interrupt factors, and 256
interrupt vector tables are assigned to the highest address. The interrupt vector is
shared by all interrupts.
A software interrupt may use all of the above interrupts (INT0 to INT256), although
parts of interrupt vectors are shared by hardware interrupt and exception processing
interrupt. A hardware interrupt has a specific interrupt vector and interrupt control
register (ICR) for each peripheral function.
I Interrupt vector
Interrupt vector tables referenced during interrupt processing are assigned to the memory area
of the highest address ("FFFC00
processing, hardware interrupt, and software interrupt share the same area.
"Interrupt vectors" lists the assignment of interrupt numbers to interrupt vectors.

For interrupt vectors that are not used, Fujitsu recommends specifying such vectors for the
address for exception processing.
