5.3.2
There are 47 sources in the H8S/2648, H8S/2648R, and H8S/2647 and 43 sources in the
H8S/2646, H8S/2646R, and H8S/2645 for internal interrupts from on-chip supporting modules.
• For each on-chip supporting module there are flags that indicate the interrupt request status,
• 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

Table 5.4 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. The situation when two or more
modules are set to the same priority, and priorities within a module, are fixed as shown in
table 5.4.
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.
activated by an interrupt, the interrupt control mode and interrupt mask bits are not affected.
