Section 5 Interrupt Controller
5.4.2 Internal Interrupts
The sources for internal interrupts from on-chip supporting modules have the following features:
• For each on-chip supporting module there are flags that indicate the interrupt request status,
and enable bits that select enabling or disabling of these interrupts. If both of these are set to 1
for a particular interrupt source, an interrupt request is issued to the interrupt controller.
• The interrupt priority level can be set by means of IPR.
• The DTC can be activated by a TPU, SCI, or other interrupt request.
• When the DTC is activated by an interrupt request, it is not affected by the interrupt control
mode or CPU interrupt mask bit.
5.5 Interrupt Exception Handling Vector Table
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. 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.
Note: DTC, PC break controller, and MMT interrupt sources are not implemented in the
H8S/2614 and H8S/2616.
