Hi,

I am working with kinetis L 46 micro-controller. My application is battery powered so that I want to optimize power as much as possible...

All I need to do is switch between LLS and Vlpr mode via RUN. I can able to enter into lls mode and rtc 1 sec interrupt will wake up the processor from lls mode and it will go to the Run mode and I'm changing the mcg mode to BLPI and turning OFF the clock monitor.

But PMC  REGONS bit is not turning 0.

Is there anything else that I need to do.

Please give me any suggestions.

 

Best Regards,

Shabana
