(3) 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 5.8 shows operations and control signal functions in each interrupt control mode.
Table 5.8
Legend:
X : No operation. (All interrupts enabled)
IM : Used as interrupt mask bit
PR: Sets priority.
— : Not used.
Notes: 1. Set to 1 when interrupt is accepted.
