Hi I have found the issue, after anytime the CR was updated the INIT bit was set for a short time, but enough to cause a delay. The way around it was to clear the INIT bit before locking the RTC registers again. ThanksScott

I added the line:__DSB();after the clocks being enabled, but never made a difference. But when I added a 2ms delay after GPIOB->MODE and this worked.Where do I add the DSB command, and is it just the DSB() on its own?CHeersScott

Many thanks for your reply.I havent come across this before, do I call it for all clocks, or is it 1 command takes care of it all?I can add "__DSB();" line to my code, is that all is needed? RegardsScott
