Scheduled interrupts: Interrupts generated at a specified interval based on the CPU Unit's built-in clock.
I/O interrupts: Interrupts from Interrupt Input Units or from built-in inputs (CJ1M-CPU22/23 only).
Power OFF interrupts: Interrupt executed when CPU Unit's power is turned OFF.
External interrupts: Interrupts from Special I/O Units and CPU Bus Units.
Supported using global subroutines.
