Configure RTC Alarm separately from RTC

To be able to configure the RTC Alarm in CubeMX, you have to enable it in CubeMX.

This means that all the configuration - of both the RTC itself, and the alarm - will be done in the MX_RTC_Init function - whereas I'd have thought it more likely that you'd want to configure and start the RTC itself separately from setting an alarm?

ie, you configure & start the RTC at startup, but you don't set the Alarm until some time later - when it's needed.

Is there a way to do that in CubeMX ?

Hello @Andrew Neil, 

I believe this is also related to this posted created by @TDJ : Re: CubeMX RTC config issues - STMicroelectronics Community? 

I have already submitted a ticket regarding this behavior!

Yes, that looks very similar!
