Special interrupts are non-maskable.
A watchdog timer interrupt is generated by the watchdog timer. For details, refer to 14. Watchdog Timer.
An oscillation stop detection interrupt is generated by the oscillation stop detection function. For details of the
oscillation stop detection function, refer to 9. Clock Generation Circuit.
A voltage monitor 1/comparator A1 interrupt is generated by the voltage detection circuit. A non-maskable or
maskable interrupt can be selected by IRQ1SEL bit in the CMPA register. For details of the voltage detection
circuit, refer to 6. Voltage Detection Circuit and for details of the comparator A, refer to 30. Comparator A.
A voltage monitor 2/comparator A2 interrupt is generated by the voltage detection circuit. A non-maskable or
maskable interrupt can be selected by IRQ2SEL bit in the CMPA register. For details of the voltage detection
circuit, refer to 6. Voltage Detection Circuit and for details of the comparator A, refer to 30. Comparator A.
Do not use these interrupts. They are provided exclusively for use by development tools.
An address match interrupt is generated immediately before executing an instruction that is stored at an address
indicated by registers RMAD0 to RMAD1 if the AIER00 bit in the AIER0 register or the AIER10 bit in the
AIER1 register is set to 1 (address match interrupt enabled).
For details of the address match interrupt, refer to 11.6 Address Match Interrupt.
A peripheral function interrupt is generated by a peripheral function in the MCU. Peripheral function interrupts
are maskable. Refer to Table 11.2 Relocatable Vector Tables for sources of the corresponding peripheral
function interrupt. For details of peripheral functions, refer to the descriptions of individual peripheral
functions.
