CHAPTER 12 INTERRUPT FUNCTION
12.2 Interrupt Sources and Configuration
There are a total of 13 interrupts, combining non-maskable interrupts, maskable interrupts and software interrupts
(see Table 12-1).

Notes 1. Default priorities are intended for two or more simultaneously generated maskable interrupts. 0 is the
highest priority and 9 is the lowest priority.
2. Basic configuration types (A) to (D) correspond to (A) to (D) of Figure 12-1.
