4. INTERRUPT FUNCTION
The following three types and 17 sources of interrupts are available:
• Non-maskable : 1 ^Note
• Maskable
: 16 ^Note
• Software
:1
Note One of two types of interrupt sources (INTWDT), non-maskable and maskable (internal) is selectable as
the watchdog timer interrupt source.

The default priority is used if two or more maskable interrupts occur at the same time. 0 is the highest
and 15 is the lowest.
(A) through (D) in Basic Configuration Type correspond to (A) through (D) in Figure 4-1.
