The interrupt controller (INTC) ascertains the priority of interrupt sources and controls interrupt

requests to the CPU. The INTC registers set the order of priority of each interrupt, allowing the

user to process interrupt requests according to the user-set priority.

• 16 levels of interrupt priority can be set

• NMI noise canceler function

• Occurrence of interrupt can be reported externally (IRQOUT pin)

• Register banks

By setting the fifteen interrupt priority registers, the priorities of IRQ interrupts, PINT

interrupts, and on-chip peripheral module interrupts can be selected from 16 levels for request

An NMI input-level bit indicates the NMI pin state. By reading this bit in the interrupt

exception service routine, the pin state can be checked, enabling it to be used as the noise

canceler function.

For example, when this LSI has released the bus mastership, this LSI can inform the external

bus master of occurrence of an on-chip peripheral module interrupt and request for the bus

This LSI has register banks that enable register saving and restoration required in the interrupt

processing to be performed at high speed.
