Hi, I am working with kinetis W 21D256 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 Run Mode and Vlpr mode via RUN.I'm changing the mcg mode to BLPI and turning OFF the clock monitor,SMC_PMPROT[AVLP]) is set,SIM_CLKDIV1_OUTDIV1=0,SIM_CLKDIV1_OUTDIV2=1,SIM_CLKDIV1_OUTDIV4=4. But PMC  REGONS bit is not turning 0. Is there anything else that I need to do. Please give me any suggestions.   Best Regards, Madan
