Default Priority Determination: The priority is determined for the selected interrupt, and a

vector number is generated.

If the same value is set for ICR, 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 5.7 shows operations and control signal functions in each interrupt control mode.
