5.1.1
The chip controls interrupts by means of an interrupt controller. The interrupt controller has the
following features:
• Two interrupt control modes
• Priorities settable with IPR
• Independent vector addresses
• Seven external interrupts
• DTC control *
Note: * The H8S/2635 Group is not equipped with a DTC.
