STM32F103 won't wake-up from standby when using RTC Alarm

[Costas Papachristou]

I can wake-up the STM32F103 from standby mode with an external signal on the PA0 pin. Also, the RTC alarm produces an interrupt when the MCU is not in standby mode, but when the MCU is in standby mode I cannot get it to wake-up with the RTC alarm.
