15.3 Description of Operation
15.3.1
The non-maskable NMI interrupt (NMIINT) is assigned to the NMI pin.
The NMI pin allows selection of an input mode with a pull-up resistor or a high-impedance input mode by using the
NMI control register (NMICON). At a system reset, the input mode with a pull-up resistor is selected.
The level of the NMI pin can be read by reading the NMI data register (MMID).
When a level change occurs at the NMI pin after the duration longer than the minimum NMI interrupt pulse width, a
non-maskable interrupt which does not depend on the master interrupt enable flag (MIE) is generated.
Figure 15-2 shows the NMI interrupt generation timing.
