tiny_lpm documentation? Exit stop mode causing issues.

[LHarm.1]

I have built an app based on the p2p server. I have added several tasks to read adc, drive pwm an talk to i2c devices. The app runs as expected when I disable the stop mode.

UTIL_LPM_SetStopMode(1 << CFG_LPM_***, UTIL_LPM_DISABLE);

However when I allow stop mode The app does not run as expected after exiting from stop mode. Do I need to re-initialize some things when exiting stop_mode?
