I did read the reference.
I managed to see changes in CyResetStatus, but only for watch dog and not for reset due to low voltage.
I guess the reason is that I need to implement LVD in my schematics. The problem is that I can't find this LVD unit.
I tried to use this tutorial for adding LVD. But again, couldn't find this component in the components catalog.
Can anyone help? I'm using PSoC Creator 3.3.
