OS function is provided.
: Available when a cause of interrupt sharing a same ICR is not used.
* : When interrupts of the same level are output at the same time, the interrupt with the smallest interrupt vector
number has the priority.
When there are two interrupt causes in the same interrupt control register (ICR) and use of IIOS is enabled,
IIOS is started upon detection of one of the interrupt causes. As interrupts other than the start cause are
masked during IIOS start, masking one of the interrupt requests is recommended when using IIOS.
For a resource that has two interrupt causes in the same interrupt control register (ICR), the interrupt flag is
cleared by an IIOS interrupt clear signal.
