Intrinsic Functions

Dear Community,

Sorry if this is a really simple question, but what are "intrinsic functions"? After searching the web for where the "__no_operation(); " function was defined, I came across this term. I'm using one of the CC430 RF examples and I don't see the definition for the functions that have the underscores in front of them in the files provided. Do you know where I can find these definitions so that I know what functions are available? Are they buried somewhere in the CCS4 program folder?

Thank you so much for your help!

    Intrinsic functions are functions that built into the compiler. As such they are usually specific to compiler and are not portable. The functions tend be C wrappers around assembler instructions. See your compiler user guide for more detail. In your case, this might the correct guide

    It should be in your CCS4 folder somewhere.
