21.2 Interrupt Sources and Configuration
There are total of 24 non-maskable, maskable, and software interrupts in the interrupt sources.
Table 21-1: Interrupt Source List
Notes:
1.
Default priorities are intended for two or more simultaneously generated maskable interrupt
requests. 0 is the highest priority and 26 is the lowest priority.
2.
Basic configuration types (A) to (E) correspond to (A) to (E) of Figure 21-1.
