    Hi,

      There are several ways to wake up the uC. Below are the possible wakeup sources:

    ■ External WAKE
    ■ External RST
    ■ GPIO K[7:4]
    ■ Tamper TMPR[3:0]
    ■ Tamper XOSC failure
    The Hibernation module can also be configured to wake from hibernate when the following events
    occur:
    ■ RTC match wake event
    ■ Low Battery wake event

    Please refer to the TivaWare hibernate module example in C:\ti\TivaWare_C_Series-2.2.0.295\examples\boards\ek-tm4c1294xl\hibernate. Make sure you have the respective wake up sources enabled. See below example to wake on nWAKE or GPIO or RESET or RTC.

     MAP_HibernateWakeSet(HIBERNATE_WAKE_PIN | HIBERNATE_WAKE_GPIO |
                         HIBERNATE_WAKE_RESET | HIBERNATE_WAKE_RTC);
