5.1
This LSI controls interrupts with the interrupt controller. The interrupt controller has the following
features:
• Two interrupt control modes
• Priorities settable with IPR
• Independent vector addresses
• Nine external interrupts
• DTC and DMAC* control
Note: * Supported only by the H8S/2239 Group.
⎯ 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

levels can be set for each module for all interrupts except NMI. NMI is assigned the
highest priority level of 8, also accepted (using nesting) during interrupt processing.
Additionally accepted during state 12 if Opcode = H'57F3.

edge can be selected for NMI. Falling edge, rising edge, or both edge detection, or level
sensing, can be independently selected for IRQ7 to IRQ0.
