I view the DSC56F83000 examples, I do not find the specification about these function(mult_r(), __L_mult(), __L_shrtNs(), etc.).
Do you have the specification about these? Waiting for your reply. Thanks!
I suppose that you use the #include "intrinsics_56800E.h", which defines the operation.
The "intrinsics_56800E.h" is located at the directory.
