Hello Jython, WFI is an assembler instruction. The Keil wrapper isn't available in gcc. I know of no direct replacement. Most likely you need a gcc inline assembly for that. May I ask why you would need "wfi"? If you use a operating system, the system typically handles such low level stuff for you. The only application that springs to mind for that instruction is overwriting the idle loop to save energy.
