I’m trying to put the Cerb40 in Standby mode and wakeup the Cerb using auto-wakeup. I’ve succeeded however there are still some strange things happening. At this moment I use the SLEEPONEXIT bit (see Programming Manual PM0214, Rev 3, September 2012, page 213) to put the processor into Standby mode. Better would be to use the WFI or WFE instruction. Is there a way use issue the WFI or WFE instruction in C#, like an inline assembly code?
