Section 5 Interrupt Controller
5.5
Interrupt Exception Handling Vector Table
Table 5.2 lists interrupt exception handling sources, vector address offsets, and interrupt priority.
In the default priority order, a lower vector number corresponds to a higher priority. When
interrupt control mode 2 is set, priority levels can be changed by setting the IPR contents. The
priority for interrupt sources allocated to the same level in IPR follows the default priority, that is,
they are fixed.
