10.1.3 Hardware Interrupts
Hardware interrupts are classified into two types — special interrupts and peripheral function inter-
rupts.
(1) Special Interrupts
• Watchdog Timer Interrupt
• Oscillation Stop Detection Interrupt
• Single-step Interrupt
• Address Match Interrupt
(2) Peripheral Function Interrupts
Special interrupts are non-maskable interrupts.
Generated by the watchdog timer. Once a watchdog timer interrupt is generated, be sure to initialize
the watchdog timer. For details about the watchdog timer, refer to Chapter 11, “Watchdog Timer.”
Generated by the oscillation stop detection function. For details about the oscillation stop detection
function, refer to Chapter 6, “Clock Generation Circuit.”
Do not normally use this interrupt because it is provided exclusively for use by development support
tools.
An address match interrupt is generated immediately before executing the instruction at the address
indicated by the RMAD0 to RMAD1 register that corresponds to one of the AIER register's AIER0 or
AIER1 bit which is "1" (address match interrupt enabled). For details about the address match inter-
rupt, refer to Section 10.4, “Address Match Interrupt.”
Peripheral function interrupts are maskable interrupts and generated by the microcomputer's internal
functions. The interrupt factors for peripheral function interrupts are listed in Table 10.2.
“Relocatable Vector Tables”. For details about the peripheral functions, refer to the description of
each peripheral function in this manual.
