Section 5 Interrupt Controller
Interrupt Acceptance Control: In interrupt control mode 0, interrupt acceptance is controlled by
the I bit in CCR.
Table 5.4 shows the interrupts selected in each interrupt control mode.
Table 5.4
Legend:
X:
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.
Table 5.5
Default Priority Determination: When an interrupt is selected by 8-level control, its priority is
determined and a vector number is generated.
If the same value is set for IPR, acceptance of multiple interrupts is enabled, and so only the
interrupt source with the highest priority according to the preset default priorities is selected and
has a vector number generated. Interrupt sources with a lower priority than the accepted interrupt
source are held pending.
Table 5.6 shows operations and control signal functions in each interrupt control mode.
