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

3.2

Interrupt Cause and Interrupt Vector

2
F MC-16LX has functions that are associated with 256 types of interrupt causes, and
256 interrupt vector tables are assigned to the most significant address area of memory.
This interruption vector is shared by all the interruptions.
All of interrupt INT0 to INT255 are available for software interrupt, although some
interrupt vectors are shared with hardware interrupt or exception processing interrupt.
Furthermore, for hardware interrupt, the fixed interrupt vectors and interrupt control
registers (ICR) are used for each of the peripheral functions.
Interrupt Vector
The interrupt vector table referenced during interrupt processing is assigned to the most significant of
memory address area ("FFFC00
