unable to enter STOP mode using SMC_SetPowerModeStop

tuomasaaltio — Thu, 02 Mar 2017 14:16:07 GMT

the following code fails to enter stop mode.

            SMC_PreEnterStopModes();
            SMC_SetPowerModeStop(SMC, kSMC_PartialStop);
            SMC_PostExitStopModes();

SMC_PMCTRL.STOPA is set.

What could cause this?

I have at initialization set

SMC_SetPowerModeProtection(SMC, kSMC_AllowPowerModeAll);

I would recommend customer to refer [power_manager] demo located at ..\SDK_2.1_FRDM-KL26Z\boards\frdmkl25z\demo_apps\power_manager folder.

The KSDK V2.1 .0 for FRDM-KL25Z board software, could be downloaded from here.

Wish it helps.
