Section 5 Interrupt Controller
(1) Interrupt Acceptance Control
In interrupt control mode 0, interrupt acceptance is controlled by the I bit in CCR.
Table 5-6 shows the interrupts selected in each interrupt control mode.

*: Don't care
(2) 8-Level Control
In interrupt control mode 2, 8-level mask level determination is performed for the selected
interrupts in interrupt acceptance control according to the interrupt priority level (IPR).
The interrupt source selected is the interrupt with the highest priority level, and whose priority
level set in IPR is higher than the mask level.
