• The interrupt priority is the order which is executed at the time of the multiple interrupt. The lower the
numerical value, the higher the interrupt priority.
• The interrupt priority order is the order which is executed when the interrupt factor with the same interrupt
priority is generated.
Description
interrupt pointer used for input interrupt of CPU module. Up to 8 points can be used.
Interrupt pointer used for high-speed comparison match interrupt of CPU module.
Interrupt pointer used for fixed cycle interrupt by internal timer.
Interrupt pointer used for a module that has interrupt function.
