19.1
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 handle interrupt requests according to user-set priority.
19.1.1
The INTC has the following features.
• Fifteen interrupt priority levels can be set
• NMI noise canceler function
• NMI request masking when SR.BL bit is set to 1
19.1.2
Figure 19.1 shows a block diagram of the INTC.
By setting the three interrupt priority registers, the priorities of on-chip peripheral module
interrupts can be selected from 15 levels for different request sources.
The NMI input level bit indicates the NMI pin state. The pin state can be checked by reading
this bit in the interrupt exception service routine, enabling it to be used as a noise canceler.
It is possible to select whether or not NMI requests are to be masked when the SR.BL bit is set
to 1.
