The interrupt sources include external interrupts (NMI, IRQ
5.3.1
There are seven external interrupts: NMI, and IRQ
can be used to exit software standby mode.
NMI
NMI is the highest-priority interrupt and is always accepted, regardless of the states of the I and UI
bits in CCR. The NMIEG bit in SYSCR selects whether an interrupt is requested by the rising or
falling edge of the input at the NMI pin * . NMI interrupt exception handling has vector number 7.
Note: * For the H8/3048F-ONE (single power supply with flash memory), the NMI input may

These interrupts are requested by input signals at pins IRQ
