7.1
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.
7.1.1
INTC has the following features:
• 16 levels of interrupt priority can be set: By setting the five interrupt-priority registers, the
• NMI noise canceller function: NMI input-level bit indicates NMI pin states. By reading this bit
priorities of on-chip supporting module, IRQ, and PINT interrupts can be selected from 16
levels for individual request sources.
in the interrupt exception service routine, the pin state can be checked, enabling it to be used as
a noise canceller.
