18.5 Interrupt Sources
The IIC has interrupt source IICI. Table 18.8 shows the interrupt sources and priority. Individual
interrupt sources can be enabled or disabled using the enable bits in ICCR, and are sent to the
interrupt controller independently.
The IIC interrupts are used as on-chip DTC activation sources.
