4.3
Interrupt exception handling can be requested by nine external sources (NMI and IRQ7 to IRQ0)
from 17 input pins (NMI, IRQ7 to IRQ0, and KIN7 to KIN0), and internal sources in the on-chip
supporting modules. Figure 4.4 shows 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 free-running timer (FRT), 8-bit timer (TMR), serial communication interface (SCI), data
transfer controller (DTC) (only in the H8S/2138 Group), A/D converter (ADC), host interface
(HIF) (only in the H8S/2138 Group), and I
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 and
address break to either three priority/mask levels to enable multiplexed interrupt control.
For details on interrupts, see section 5, Interrupt Controller.
Note:
Interrupts
Numbers in parentheses are the numbers of interrupt sources.
* When the watchdog timer is used as an interval timer, it generates an interrupt
request at each counter overflow.
