WebI have an application where I have 2 sources that wake my STM32F from STANDBY: RTC and wakeup pin. Both work well as designed (they wake my MCU from STANDBY) but I cannot get the flag to tell what caused the MCU to wake up: if it was the WAKE pin or RTC alarm. To be more specific, I can do that, when I start running the code with JTAG debugger.
