Interrupt Factor and Interrupt Vector

2
The F MC-16LX family has vector tables corresponding to 256 types of interrupt factor.
I Interrupt Vector
The interrupt vector tables referenced at interrupt processing are allocated to the most significant addresses
("FFFC00
exception processing, and hardware and software interrupts.
• Interrupts (INT0 to INT255) are used as software interrupts.
• At hardware interrupts, the interrupt vectors and interrupt control register (ICR) are fixed for each
resource.
Figure 3.5-1 shows the interrupt number and allocation of interrupt vector.
