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.
6.1
• 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
sources.
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
mastership.
This LSI has register banks that enable register saving and restoration required in the interrupt
processing to be performed at high speed.
