Interrupt exception handling can be requested by nine external sources (NMI, IRQ7 to IRQ0) and 52 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), refresh timer, 16-bit
timer-pulse unit (TPU), 8-bit timer, serial communication interface (SCI), data transfer controller (DTC), DMA controller
(DMAC), 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.
