5. Interrupt Controller
5.3
The interrupt sources include external interrupts (NMI, IRQ
5.3.1
There are seven external interrupts: NMI, and IRQ
IRQ
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.
IRQ
The IRQ
• 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
• The status of IRQ
