The NMI supports the same features as the external interrupts, and is accessed through the
same registers. The description in
instead of the INTn bits.
The NMI is non-maskable within the CPU in the sense that it can interrupt any other execution
mode. Still, as for the other external interrupts, the actual NMI input can be enabled and disabled
by accessing the registers in the EIC.
Each external interrupt can be made asynchronous by writing a one to INTn in the ASYNC reg-
ister. This will route the interrupt signal through the asynchronous path of the module. All edge
interrupts will be interpreted as level interrupts and the filter is disabled. If an interrupt is config-
ured as edge triggered interrupt in asynchronous mode, a zero in EDGE.INTn will be interpreted
as low level, and a one in EDGE.INTn will be interpreted as high level.
EIC_WAKE will be set immediately after the source triggers the interrupt, while the correspond-
ing bit in ISR and the interrupt to the interrupt controller will be set on the next rising edge of
CLK_SYNC. Please refer to
Figure 16-4 on page 293
Section 16.6.1
should be followed, accessing the NMI bit
for details.
