6.3.3
Interrupt Exception Vector Table
Table 6.4 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 ICR. The situation when two or more modules
are set to the same priority, and priorities within a module, are fixed as shown in table 6.4.
