Hello Forum, is there anybody who has implemented the Inter-IC-Sound protocol with a 80C167? It's a simple synchronous serial protocol, the C167's SSC seems to be o. k. for that, but with the exception of the word strobe signal: The Clock is continously running. To recognize the first bit of a word (and synchronize the SSC) it must be synchronized with the word strobe signal. My first (only mental) approach is to clear SSCBC on a transition of word strobe signal. This could be done via Pec, but eventually this isn't fast enough. In addition, the manual claims: "Do not write to SSCBC!!!" Any ideas are welcome! Thanks - Peter
Hello, that sounds just fine. I'll do some thoughts about that. THANKS. Maybe sending $FF00 and do an exor externally, which output will be synchronized. BTW: Did you implement an I²C master or slave? Did you implement I²C with SSC including Clock Longing? With "clock longing" I mean the possibility for slaves (and masters) to delay transfers by pulling clock low? Greeting - Peter
