Hello, I write some code for a microcontroller (251 family) in C language. depending on some stuff, i will continue in a way or another way, so i will call the desired function as Function(); This will lead to an ECALL in asm, which mean PC up on the stack.. How can i explain to compiler that a EJMP is desired in my case, i do not need to come back ever, i do not need the PC on the stack (remember, i do this in C...) The function called is (also) in another C file (not the same file), where there are more files into one project. Any suggestion would be appreciated, thanX
