Edge-sensed interrupt signals are latched (if enabled) until the interrupt is serviced. They are
latched even if the interrupt mask bit (I) is set in the CCR, and remain latched even if the enable bit

After a reset, all IRQi interrupts are disabled (as well as masked).

4.2.2 External Interrupts
The external interrupts are NMI and IRQ
(1) NMI: A nonmaskable interrupt is generated on the rising or falling edge of the NMI input
signal regardless of whether the I (interrupt mask) bit is set in the CCR. The valid edge is selected
by the NMIEG bit in the system control register.
An NMI has highest priority and is always accepted as soon as the current instruction ends, unless
the current instruction is an ANDC, ORC, XORC, or LDC instruction. When an NMI interrupt is
