Hi guys,

I have got an issue where the RTCC interrupt keeps firing in the middle of my subroutine. I have put in code to turn the interrupt off in the subroutine before I do anything and then turn it back on after I have finished. Can I actually do this? As it doesn't seem to be working. If I turn the interrupt off at the beginning of the code, it runs perfectly. 

SX48 Datasheet doesn't offer much information on this. 

Any tips or suggestions, the interrupt has to stay as it is used as a base timer for timeouts in other subroutines. 

Cheers
