21.2 Interrupt Sources and Configuration
Combining all the factors in interrupts, non-maskable interrupts, maskable interrupts and software interrupts, there
are a total of 22 source (see Table 21-1).

Notes 1. Default priorities are intended for two or more simultaneously generated maskable interrupts. 0 is the
highest priority and 18 is the lowest priority.
2. Basic configuration types (A) to (E) correspond to (A) to (E) of Figure 21-1.
