Figure 5-4 shows a block diagram of the priority decision circuit.
(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.
Table 5-6
(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.
