An example of the transition from the

enabled all factors to the disabled in the

interrupt operation.

External Interrupt-1

Process

The interrupt operation does

not execute after the prior

operation end.

* When the interrupt is enabled, the latest interrupt request occurred during the prior other interrupt process

starts its interrupt process after the prior interrupt operation. However, when the interrupt is disabled

during the prior interrupt process as shown in above timing chart, the latest interrupt request does not start.

But the prior interrupt process is completed.
