Special interrupts are non-maskable interrupts.
The watchdog timer interrupt is generated by the watchdog timer. For details, refer to 13. Watchdog Timer.
Oscillation Stop Detection Interrupt is generated by the oscillation stop detection function. For details of the
oscillation stop detection function, refer to 10. Clock Generation Circuit.
The voltage monitor 2 interrupt is generated by the voltage detection circuit. For details of the voltage
detection circuit, refer to 6. Voltage Detection Circuit.
Do not use the single-step interrupt. For development tools only.
The address match interrupt is generated immediately before executing an instruction that is stored into an
address indicated by the RMAD0 to RMAD1 registers when the AIER0 or AIER1 bit in the AIER register
which is set to 1 (address match interrupt enable).
For details of the address match interrupt, refer to 12.5 Address Match Interrupt.
The peripheral function interrupt is generated by the internal peripheral function of the MCU and a maskable
interrupt. Refer to Table 12.2 Relocatable Vector Tables for sources of the peripheral function interrupt. For
details of the peripheral function, refer to the description of each peripheral function.
