I don't know this specific processor but most times you need to initialize some default stuff. Like setting some interupts or disabling them if unused. You need to check out the datasheet to see what the defaults are. Also, check out some examples code. Most manufacturers provide example code. Check the link for more info.

Not sure what you mean by writing c functions in assembly because you can't write c functions directly in assembly. So that is somewhat confusing. Did you check out the CCES examples for your processor model?
