Hi everyone and again I hope some of you can help me with that:
I am trying to save some variables when Vdda and /or Vddd drop down 2.95 V.
I have tried to adapt the example "D" on AN 54460 for Low voltage interrupt.
I have created a small project to test the LVI feature.
To verify that the ISR is working I have set the variable "Led_On" inside the ISR.
Later in the main loop, when Vddd or Vdda drop below the threshold, I should see the led connected to the Pin 1(2) turn on a some fraction of second .
That not happen, I do not know what is missing.
Thank you very much for any help.

Hi Alex,
Files didn't get successfully attached. Can you attach again please ?
Below are the registers you need to write to generate LVI interrupts.
We discussed in this thread, is it related to the same.

Did you -
1) Placed Global Signal Component and choose the LVI configuration ?
2) Start the attached isr to the Global Signal component
3) Enable global interrupts with CyGlobalIntEnable; /* Enable global interrupts. */
4) Written your C interupt and started it correctly -
