12.5.2
Non-maskable interrupts
The Wakeup Unit supports one non-maskable interrupt that is allocated to the following pins:
•
100-pin LQFP: Pin 7
•
144-pin LQFP: Pin 11
•
176-pin LQFP: Pin 19
The Wakeup Unit supports the generation of three types of interrupts from the NMI. The Wakeup Unit
supports the capturing of a second event per NMI input before the interrupt is cleared, thus reducing the
chance of losing an NMI event.
Each NMI passes through a bypassable analog glitch filter.
NOTE
Glitch filter control and pad configuration should be done while the NMI is
disabled in order to avoid erroneous triggering by glitches caused by the
configuration process itself.
