    Hi Aili,

       I don't think the TI-RTOS has  power management API support for TM4C. If you want to use the Hibernation module for power saving you will need to use the TivaWare API to enable Hibernation and RTC. There is a hibernation example in the latest TivaWare version (version 2.2.0) for TM4C123 that you can reference in <TivaWare_Installation>/examples/boards/ek-tm4c123gxl/hibernation. Once you enable hibernation mode, the system clock is stopped until a wakeup event is detected.
