instruction (reit or freit)
If the interrupt control register is being rewritten within the non-maskable interrupt routine, add the
below processing to the end of all interrupts.
If rewriting the interrupt control register for interrupt B with the interrupt A routine and enabling multiple
interrupts with interrupt C, the above processing is required at the end of the interrupt A and interrupt
C routines.
Interrupt_A:

To rewrite the interrupt control register within the interrupt routine, add the below processing to the
end of the routine (immediately before the reit or freit instruction). Also, if multiple interrupts are
enabled with other interrupts, add the below processing to the end of the interrupt that enables the
multiple interrupts.
