Section 4 Exception Handling
4.4
Interrupt exception handling can be requested by seven external sources (NMI, IRQ5 to IRQ0) and
49 internal sources in the on-chip supporting modules. Figure 4-4 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), serial communication interface (SCI), data transfer controller
(DTC), PC break controller (PBC), A/D converter, controller area network (HCAN), motor control
PWM timer, and I
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: The DTC, PBC, and IIC are not implemented in the H8S/2635 Group.
