6.2 Interrupt Factor and Interrupt Vector

2
The F MC-16LX has functions corresponding to 256 types of interrupt factor, and 256 sets of interrupt vector
tables are allocated to the most significant addresses. The interrupt vectors are shared by all interrupts.
The software interrupt can use all interrupts (INT0 to INT256), but some interrupt vectors are shared by
hardware interrupt and exception handling interrupts. For the hardware interrupt, the interrupt vectors and
the interrupt control register (ICR) are fixed for each resource.
