5.4.1
There are two external interrupts: NMI and IRQ7 to IRQ0. These interrupts can be used to restore
this LSI from software standby mode.
NMI Interrupt: NMI is the highest-priority interrupt, and is always accepted by the CPU
regardless of the interrupt control mode or the status of the CPU interrupt mask bits. The NMIEG
bit in SYSCR can be used to select whether an interrupt is requested at a rising edge or a falling
edge on the NMI pin.
IRQ7 to IRQ0 Interrupts: Interrupts IRQ7 to IRQ0 are requested by an input signal at pins IRQ7
to IRQ0. Interrupts IRQ7 to IRQ0 have the following features:
• The interrupt exception handling for interrupt requests IRQ7 to IRQ0 can be started at an
• Using ISCR, it is possible to select whether an interrupt is generated by a low level, falling
• Enabling or disabling of interrupt requests IRQ7 to IRQ0 can be selected with IER.
• The status of interrupt requests IRQ7 to IRQ0 is indicated in ISR. ISR flags can be cleared to 0
The detection of IRQ7 to IRQ0 interrupts does not depend on whether the relevant pin has been
set for input or output. However, when a pin is used as an external interrupt input pin, do not clear
the corresponding port DDR to 0 to use the pin as an I/O pin for another function.
