Figure 7-10: Example of Processing Interrupt Requests Simultaneously Generated

Caution: The values of the EIPC and EIPSW registers must be saved before executing multiple

interrupts. When returning from multiple interrupt servicing, restore the values of
EIPC and EIPSW after executing the DI instruction.

Default priority
a > b > c

Main routine

EI

Interrupt request a (level 2)
Interrupt request b (level 1)
Interrupt request c (level 1)

Processing of interrupt request b

.

.

Processing of interrupt request c

Processing of interrupt request a

Interrupt request b and c are
acknowledged first according to
their priorities.
Because the priorities of b and c are
the same, b is acknowledged first
according to the default priority.
