5.3
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: n = 5 to 0
ISCR settings can select whether an interrupt is requested by the low level of the input at pins

IER settings can enable or disable the IRQ
