13.1.3

Special Interrupts

Special interrupts are non-maskable. However, the comparator 1 and comparator 2 can select maskable

interrupts, too.

13.1.3.1

Watchdog Timer Interrupt

The watchdog timer interrupt is generated by the watchdog timer. For details of the watchdog timer, refer to 16.

Watchdog Timer.

13.1.3.2

Voltage Monitor 1 Interrupt

The voltage monitor 1 interrupt is generated by the voltage monitor 1 circuit. For details of the voltage monitor

1 circuit, refer to 6. Voltage Detection Circuit.

13.1.3.3

Voltage Monitor 2 Interrupt

The voltage monitor 2 interrupt is generated by the voltage monitor 2 circuit. For details of the voltage monitor

2, refer to 6. Voltage Detection Circuit.

13.1.3.4

Comparator 1 Interrupt

The comparator 1 interrupt is generated by the comparator 1. The non-maskable interrupt or maskable interrupt

can be selected. For details of the comparator 1 interrupt, refer to 7. Comparator.

13.1.3.5

Comparator 2 Interrupt

The comparator 2 interrupt is generated by the comparator 2. The non-maskable interrupt or maskable interrupt

can be selected. For details of the comparator 2 interrupt, refer to 7. Comparator.

13.1.3.6

Single-Step Interrupt, and Address Break Interrupt

Do not use these interrupts. They are for use by development tools only.

13.1.3.7

Address Match Interrupt

The address match interrupt is generated immediately before executing an instruction that is stored at an

address indicated by registers RMAD0 to RMAD1 when the AIER0 or AIER1 bit in the AIER register is set to

1 (address match interrupt enable). For details of the address match interrupt, refer to 13.4 Address Match

Interrupt.

13.1.4

Peripheral Function Interrupt

The peripheral function interrupt is generated by the internal peripheral function of the MCU and is a maskable

interrupt. Refer to Table 13.2 Relocatable Vector Tables for sources of the peripheral function interrupt. For

details of peripheral functions, refer to the descriptions of individual peripheral functions.
