Hi,

I am using STM32L151VBT6 controller. The problem which i am facing is only one wake up source can wake up my MCU from Standby mode, that is either RTC alarm or wake up pin. if i used the both sources, only wake up pin can wake up the MCU from the standby mode please help me in this regard.

/* Configure the Power Good line interrupt as a wakeup source */
PWR_WakeUpPinCmd(PWR_WakeUpPin_1, ENABLE);
RTC_Set_Alarm();//wake up every 15 minutes
CLOCK_Enter_StandBy_Mode();

thank you. #wake-up-from-standby-mode
