RTC wakeup not working

[udilevy]

Hi,

I have a code that is using STM8L151C6 MCU. I'm using the RTC to wake up periodically from Halt, but for some reason when I use SPI when I'm in RUN mode , after some duration the RTC stops generating the wakeup interrupt.

when I comment the SPI procedure it all works well.

Anyone have an ididea why this is happening?

Thanks
