5.1
This LSI controls interrupts with the interrupt controller. The interrupt controller has the following
features:
• Two interrupt control modes (H8S/2268 Group only)
• Priorities settable with IPR (H8S/2268 Group only)
• Independent vector addresses
• External interrupts
• DTC control (H8S/2268 Group only)
A block diagram of the interrupt controller for the H8S/2268 Group is shown in figure 5.1, and
that for the H8S/2264 Group is shown in figure 5.2
⎯ Any of two interrupt control modes can be set by means of the INTM1 and INTM0 bits in
⎯ An interrupt priority register (IPR) is provided for setting interrupt priorities. Eight priority
⎯ All interrupt sources except WKP7 to WKP0 are assigned independent vector addresses,
H8S/2268 Group: 14 (NMI, IRQ5 to IRQ3, IRQ1, IRQ0, and WKP7 to WKP0)
H8S/2264 Group: 13 (NMI, IRQ4, IRQ3, IRQ1, IRQ0, and WKP7 to WKP0)

levels can be set for each module for all interrupts except NMI. NMI is assigned the
highest priority level of 8, and can be accepted at all times.
making it unnecessary for the source to be identified in the interrupt handling routine.
edge can be selected for NMI. Falling edge, rising edge, or both edge detection, or level
sensing, can be independently selected for IRQ5 to IRQ3, IRQ1, and IRQ0.
WKP7 to WKP0 are accepted at a falling edge
