Power management: Active Mode support?

I am running uclinux on a Blackfin 527.  I am always in Full On mode of the Blackfin.  I would like to lower my power consumption during periods of low activity.


I can't use Sleep mode because I need some CCLKs because my application has to continue running to maintain communications with another system even during inactive times.  I may be able to use Active mode.   Does uclinux offer support for entering Active mode and then programatically switching back to Full On mode?  I only saw linux support for standby (sleep or deep sleep) and for mem (hibernate), both of which would stop CCLK so I can not use them.
