How to solve this warning? I tried many ways, and still have this warning.

*** WARNING L16: UNCALLED FUNCTION, IGNORED FOR OVERLAY PROCESS NAME: REQUEST_CAM_TYPE/CAM
Normally, the function call from the Assembly code module to the C code module that has that function delclared will cause this error. Even if the C function is very simple Void Funct(Void) with out passing any parameters or pointer. nope, calling C from asm works well if you have a main() in C

Yes, Erik.
My main is in C. I have main() in C.
But my interrupt handler is in Assembky named DR232A.ASM. And from this assembly module, if I call the funtion which is declared in the C module. Then the LX51 will give the warning error. If my main() in C calls this function, then there is no warning error.
