The Communications Protocol Manual?
You might look at related car radio ICs, or infotainment system software, etc
Suspect probably covered by NDA/SLA, or commercial confidential between Philips(NXP) or STMicro, etc
Assuming you're not likely to make much headway via this path, perhaps stick a protocol analyzer, or logic analyzer on it an look at it that way.

Thank you! But I don't have any car radio to see this information! I am projecting a personal AM/FM radio. I had search a lot for this information, and I found that there are a lot of companies that uses it, including chineses, not only Philips! I am tired to seek for this SECRET information in an such simple device. I will buy a cheap car radio and do reverse engineering, that's the only way! What an terrible situation! What can be so Confidential in a such obsolete and simple device? I thin ST could be more flexible some times!
Thank you anyway!

Unfortunately, it is not so simple because I don't know the registers to PLL computing. I hooked a logic analyzer, but there are lots of things that I cannot understand because I don't have the damn communication protocol.
It is very strange that this component be held in such “restricted�? information. It is considered as “obsolete�?. Well, I already spend a lot of money and effort trying to figure out how to access this chip! I give up, will try the development with another TUNER IC, of course, with different brand this time. It is a shame!
Thank you anyway!
