15.5 Interrupt Source
The IIC interrupt source is IICI. The IIC interrupt sources and their priority order are shown in
table 15.10. Each interrupt source is enabled or disabled by the ICCR interrupt enable bit and
transferred to the interrupt controller independently.
The IICI0 to IICI3 interrupts can be used as sources of activating the on-chip DTC.
