The detection of IRQ7 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 to use the pin as an I/O pin for another function. The IRQ7F to
IRQ0F interrupt request flags can be set to 1 when the setting condition is satisfied, regardless of
IER settings. Accordingly, refer to only necessary flags.
5.4.2
For each on-chip peripheral 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 sent to the interrupt controller.
5.4.3
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.
