Dears:

Could you kindly help to provide the code of TM4C1230H6PM under deep sleep?

The customer's code as below, is there any issue about it?

/*在睡眠模式下关闭所有外设*/
    SysCtlPeripheralClockGating(true);
    /*设置Deep-Sleep下的时钟源*/
    SysCtlDeepSleepClockConfigSet(2, SYSCTL_DSLP_OSC_INT30 | SYSCTL_DSLP_PIOSC_PD);
    /*在深睡眠模式下使能GPIO管脚*/
    SysCtlPeripheralDeepSleepEnable(SYSCTL_PERIPH_GPIOF);
    
    GIZWITS_LOG(RT_DEBUG_TRACE, ("Enter deep sleep\n"));
    SleepSecond(1);
    /*系统进入Deep-Sleep*/
    SysCtlDeepSleep();

Is there any query, pls. feel free to let me know!
