8. INTERRUPT FUNCTION
Notes 1. The default priority determines the sequence of interrupts if two or more maskable interrupts occur
Maskable
Interrupt
A total of 42 interrupt sources are provided, divided into the following two types.
Type
• Maskable interrupt: 41
• Software interrupt: 1
2. Basic configuration types (A) to (C) correspond to (A) to (C) in Figure 8-1.
3. When bit 7 (WDTINT) of the option byte (000C0H) is set to 1.
4. When bit 1 (LVIMD) of the low-voltage detection register (LVIM) is cleared to 0.
simultaneously. Zero indicates the highest priority and 40 indicates the lowest priority.
