Section 5 Interrupt Controller
A block diagram of IRQn interrupts is shown in figure 5.2.
5.4.2
The sources for internal interrupts from on-chip peripheral modules have the following features:
• For each on-chip peripheral module there are flags that indicate the interrupt request status,
• The interrupt priority level can be set by means of IPR.
• The DMAC and DTC can be activated by a TPU, SCI, or other interrupt request.
• When the DMAC or DTC is activated by an interrupt request, it is not affected by the interrupt

independently. When the enable bit is set to 1, an interrupt request is issued to the interrupt
controller.
