Interrupt exception handling can be requested by seven external sources (NMI, IRQ
36 internal sources in the on-chip supporting modules. Figure 4.4 classifies the interrupt sources
and indicates the number of interrupts of each type.
The on-chip supporting modules that can request interrupts are the watchdog timer (WDT),
DRAM interface, 16-bit timer, 8-bit timer, DMA controller (DMAC), serial communication
interface (SCI), and A/D converter. Each interrupt source has a separate vector address.
NMI is the highest-priority interrupt and is always accepted*. Interrupts are controlled by the
interrupt controller. The interrupt controller can assign interrupts other than NMI to two priority
levels, and arbitrate between simultaneous interrupts. Interrupt priorities are assigned in interrupt
priority registers A and B (IPRA and IPRB) in the interrupt controller.
Note: * NMI input is sometimes disabled when flash memory is being programmed or erased. For
For details on interrupts see section 5, Interrupt Controller.
Notes: Numbers in parentheses are the number of interrupt sources.
details see section 18.4.5 Flash Vector Address Control Register (FVACR).
*1 When the watchdog timer is used as an interval timer, it generates an interrupt request
*2 When the DRAM interface is used as an interval timer, it generates an interrupt request
