Section 5 Interrupt Controller
5.7.6 NMI Interrupt Usage Notes
The NMI interrupt is part of the exception processing performed cooperatively by the LSI’s
internal interrupt controller and the CPU when the system is operating normally under the
specified electrical conditions. No operations, including NMI interrupts, are guaranteed when
operation is not normal (runaway status) due to software problems or abnormal input to the LSI’s
pins. In such cases, the LSI may be restored to the normal program execution state by applying an
external reset.
