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
5.5
Table 5.2 shows interrupt exception handling sources, vector addresses, and interrupt priorities.
For default priorities, the lower the vector number, the higher the priority. When interrupt control
mode 2 is set, priorities among modules can be set by means of the IPR. Modules set at the same
priority will conform to their default priorities. Priorities within a module are fixed.

and enable bits that select enabling or disabling of these interrupts. They can be controlled
independently. When the enable bit is set to 1, an interrupt request is issued to the interrupt
controller.
