Section 5 Interrupt Controller
5.4.2
Internal interrupts issued from the on-chip peripheral modules have the following features:
1. For each on-chip peripheral module there are flags that indicate the interrupt request status,
2. The control level for each interrupt can be set by ICR.
3. The DTC can be activated by an interrupt request from an on-chip peripheral module.
4. An interrupt request that activates the DTC is not affected by the interrupt control mode or the
