Dear all, When I am writing some ASM function, I always need to PUSH the accumulator and all register I have used inside the function. I am wondering if this ASM function is to be called by other C function, do I still need to PUSH the accumulator and the register? It seems that the C compiler will avoid saving some useful data into the accumulator and the register that may need to be retrived after the ASM function call. Best Regards, H.K. Chan
