4.4
Interrupt exception handling can be requested by nine external sources (NMI, IRQ7 to IRQ0) and
43 internal sources in the on-chip supporting modules. Figure 4.3 classifies the interrupt sources
and the number of interrupts of each type.
The on-chip supporting modules that can request interrupts include the watchdog timer (WDT),
16-bit timer-pulse unit (TPU), 8-bit timer, serial communication interface (SCI), data transfer
controller (DTC), and A/D converter. Each interrupt source has a separate vector address.
NMI is the highest-priority interrupt. Interrupts are controlled by the interrupt controller. The
interrupt controller has two interrupt control modes and can assign interrupts other than NMI to
eight priority/mask levels to enable multiplexed interrupt control.
For details of interrupts, see section 5, Interrupt Controller.
Notes: Numbers in parentheses are the numbers of interrupt sources.
* When the watchdog timer is used as an interval timer, it generates an interrupt request
