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.
8.1
The INTC has the following features:
• 16 levels of interrupt priority can be set
• NMI noise canceler function
• IRQ interrupts can be set
• Interrupt request signal can be externally output (IRQOUT pin)
8.1.1
Figure 8.1 shows a block diagram of the INTC.
By setting the interrupt-priority registers, the priorities of on-chip peripheral modules, and IRQ
interrupts can be selected from 16 levels for individual 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 a noise
canceler.
Detection of low level, rising edge, falling edge, or high level
The bus mastership can be requested by notifying the external bus master that the external
interrupt and on-chip peripheral module interrupt requests have been generated.
