Notes 1. Priority is the priority order when more than one maskable interrupt request is generated at the same
time. 0 is the highest priority and 21 is the lowest.
2. Basic configuration types (A), (B), and (C) correspond to (A), (B), and (C) in Figure 16-1.
Remark Only one of the two watchdog timer interrupt (INTWDT) sources, non-maskable or maskable (internal),
can be selected.
