Hi Damian, I hope you're doing well!

From the attached log, I can see that the xPSR register indicates that there's an NMI exception in the chip:

xPSR: F1000002

The 2 indicates an NMI exception.

Could you please confirm the connection of the NMI_b pin in the KL46 to ensure that the interrupt is not being called?

For more information, could you please take a look at the KL46Z's Datasheet?

Please let me know if you continue to have issues.

Best regards,
Sebastian
