7.5 Interrupts

This chapter describes routes, sources and required settings of interrupts.

The CPU is notified of interrupt requests by the interrupt signal from each interrupt source.

It sets priority on interrupts and handles an interrupt request with the highest priority.

Interrupt requests for clearing a standby mode are notified to the CPU via the clock generator. Therefore, appro-

priate settings must be made in the clock generator.

7.5.1 Interrupt Sources

7.5.1.1 Interrupt Route

Figure 7-1 shows an interrupt request route.

The interrupts issued by the peripheral function that is not used to release standby are directly input to

the CPU (route 1).

The peripheral function interrupts used to release standby (route 2) and interrupts from the external inter-

rupt pin (route 3) are input to the clock generator and are input to the CPU through the logic for releas-

ing standby (route 4 and 5).

If interrupts from the external interrupt pins are not used to release standby, they are directly input to

the CPU, not through the logic for standby release (route 6).
