#139263 - It is a true 51 derivative, but Responding to: ???'s previous message |
the data sheet is just wrong about the PUSH instruction.
The 80C154 is a quite old controller, no longer used today. I have tested this with a real processor yesterday. My failure was, to trust the data sheet before publishing it in this forum. However, before I would have used it in a real application, I would have tested really it. So just forget it, it is a wrong data sheet. Best regards Juergen |
