Compiler/TMS320F28377D: How to swap 16-bit?

Hi,

Is there any function to swap 16-bit variable (first byte with second byte)? I can of course swap it manually, but I wonder if there is a dedicated function.

Thanks.

No, I don't know of any function or instruction to do that. You'll need to write something yourself. You could try experimenting with the __byte() intrinsic to see if it gets you any better performance than shifting and adding in C.

Hi Mubin,

Also see the below e2e thread. There is a C28x architecture instruction to swap the bytes, but if you want to use this you need to create a callable assembly function.
