DI, EI, IMASK
1. An interrupt pointer occupies 1 step.
2. For the information on interrupt conditions, link direct devices, refer to the QnUCPU User's Manual (Function Explanation,
Program Fundamentals) or Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals)
3. The DI state (interrupt disabled) is active during the execution of an interrupt program. Do not insert the EI instructions in
interrupt programs to attempt the execution of multiple interrupts, with interrupt programs running inside interrupt
programs.
4. If there are the EI and DI instructions within a master control, these instructions will be executed regardless of the
execution/non-execution status of the MC instruction.
