Interrupt request a (level 2)
Interrupt request b (level 1)
Interrupt request c (level 1)
Notes 1. Higher default priority
Caution To service multiple interrupts, the values of the EIPC and EIPSW registers must be saved
Remarks 1. a to c in the figure are the temporary names of interrupt request signals shown for the sake of
Default priority
a > b > c
2. Lower default priority
2. The default priority in the figure indicates the relative priority between two interrupt request
before executing the EI instruction. When returning from multiple interrupt servicing, restore
the values of EIPC and EIPSW after executing the DI instruction.

.
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.
