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.
