Section 5 Interrupt Controller
Detection of IRQ5 to IRQ0 interrupts does not depend on whether the relevant pin has been set for
input or output. However, when a pin is used as an external interrupt input pin, do not clear the
corresponding DDR to 0 and use the pin as an I/O pin for another function.
5.3.2
There are 48 sources for internal interrupts from on-chip supporting modules in the H8S/2626
Group, and 47 in the H8S/2623 Group.
5.3.3
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.

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, 8-bit timer, SCI, or other interrupt request. When the
DTC is activated by an interrupt, the interrupt control mode and interrupt mask bits are not
affected.
